Comment: The lessons learned taking my femtech idea to prototype

Published

By Muna Daud, founder of FlowSense, the world’s first period detection device designed to help women with visual impairments to independently manage their menstrual health.

As an innovation expert, I’ve created a portfolio of ideas over the years, but one has gone to prototype – FlowSense, the world’s first patented period detection device that empowers visually impaired women to independently manage their menstrual hygiene.

Created as a project during my Master’s studies at Imperial College London, I knew I couldn’t let FlowSense just be another university project – I knew the impact that it would have and decided to follow it as a venture.

These are my learnings from start to prototype throughout the development of FlowSense.

Know your ‘why’

Before you even begin sketching out your idea, take a moment to ask yourself, “Why am I doing this?” In the early stages, it’s easy to get overwhelmed by inspiration. Before diving into the details, it’s important to take a moment to break down what truly matters about your idea. Ask yourself what problem you are solving and who you are solving it for, but most importantly, why your setting out to find a solution in the first place.

The ‘why’ for FlowSense came out of an already pre-existing interest in women’s health – particularly menstrual health. I had previously designed DAILYA, underwear with embedded heating to target menstrual cramps, which I put on hold to focus on FlowSense.

FlowSense began from learning about the struggles many visually impaired women face when managing their menstrual health. I knew this unmet need had to be addressed, and asking myself, ‘why not?’ I embarked on a journey of developing a solution for menstrual hygiene for those with visual impairments.

Find your Focus

In a world full of problems to solve, it’s tempting to try to tackle everything at once. But one of the most valuable lessons I learned is to narrow your focus. Instead of solving ten problems halfway, focus on solving one problem well.

For FlowSense, this meant zeroing in on one specific issue: the challenge of distinguishing menstrual blood from other bodily discharges.

While there are many challenges visually impaired women face when managing their periods, solving this issue has the potential to make an immediate and tangible difference in their lives. This focus guided every step of my process, ensuring that my energy wasn’t scattered across too many directions.

Identify your idea

Once you’ve found your focus, the next step is turning the problem into an actionable idea. For me, this involved brainstorming solutions that could make menstrual blood detection simple, accessible, and non-invasive for visually impaired women.

From research, I landed upon using pH as a detecting method, turning to finding methods to make this identifiable outside of traditional pH testing strips.

FlowSense’s early design was based on the fact that menstrual blood has a different pH compared to other vaginal discharges. Using this insight, I wanted to create a modified sanitary pad that would be able to respond to the different pH levels of vaginal fluids, and allows the visually impaired woman to detect periods for themselves through senses other than sight.

Bringing it to life

Turning an idea into reality is where the true challenges lie. This phase requires bridging the gap between concept and execution through innovation, experimentation, and relentless problem-solving.

For FlowSense, this meant going beyond theoretical designs and creating something functional, sustainable, and accessible – a biodegradable polymer tactile pad.

Research for this started in December 2022, with one of the key breakthroughs came from using the biodegradable polymer chitosan.

Chitosan is derived from chitin, a natural substance found in the shells of crustaceans, and has remarkable properties that make it perfect for FlowSense.

Not only is it biocompatible and environmentally friendly, but it also reacts to changes in pH – as chitosan swell in acidic vaginal discharge fluid and shrinks in alkaline period blood – a critical aspect of menstrual blood detection.

Our early prototypes used chitosan in pH-sensitive strips integrated into sanitary pads. When exposed to menstrual blood, the polymer would react and change its structure, providing a tactile signal that users could detect. This innovation offered a discreet and reliable way for visually impaired women to identify menstrual onset without visual cues.

This stage underscored the importance of selecting the right materials and embracing the iterative nature of product development. Chitosan wasn’t just a functional material – it became the cornerstone of bringing FlowSense to life.

Get users onboard

No matter how brilliant your idea may seem, it’s the users who ultimately determine its success. Getting feedback from your target audience early and often is essential to creating something that truly meets their needs.

For FlowSense, I partnered with the Royal National Institute of Blind People to connect with visually impaired women who could test our prototypes. Their insights were invaluable. They told us what worked, what didn’t, and what could be improved.

One of the most important insights came from the tactile element of the pad. While the idea of using a tactile signal for menstrual blood detection seemed straightforward during development, users raised concerns about hygiene and ease of use.

Handling the pad to detect the change wasn’t intuitive for some and felt unhygienic, particularly in situations where access to soap and water was limited. This highlighted the importance of designing solutions that not only work but also respect the practical realities of users’ daily lives.

Engaging with users also deepened my understanding of the problem we were trying to solve. It wasn’t just about detecting menstrual blood – it was about providing a tool that seamlessly fit into their lives, respected their privacy, and boosted their confidence.

Hold onto your first inspiration

Every journey from idea to product comes with setbacks, but holding onto your original inspirations keeps you grounded. Often, even if the first iteration of the idea doesn’t work out, the failures of that first iteration and the original focus will help build an even better product further down the line.

For FlowSense, the original tactile pad design didn’t work as intended, but the idea of using pH is still the focus while I work on the new working prototype, which I shifted focus onto in May 2023.

It was the tactile element that users did not like, so we’ve now shifted to seeing how pH detection can be used for audio or vibration cues instead.

I wanted to create a product that goes with the flow of user’s routines and preferences rather than forcing an idea that worked on paper but was not practical.

By combining the original pH testing pad idea with technology, I’m now working on a device that not only expands on the technology out there for menstrual health, but also widens the support FlowSense can offer by having a cycle tracking app connected to the device.

Through prototyping, FlowSense has evolved into a holistic solution for menstrual health, combining hygiene, tracking, and vaginal health diagnostics—a true testament to how technology can empower women’s well-being.

Future applications, like expanding vaginal pH analysis to all women for broader diagnostics, highlight its potential to revolutionise care. None of this would have been possible without listening to the women we designed for, proving the power of creating a device for women, by women.

Yoga and omega-3 as effective as therapy for depression in pregnancy, research finds

Published

on

Yoga and omega-3 supplements may be as effective as talking therapies for pregnancy depression, a major review suggests.

Globally, nearly one in three pregnant women experience depression, but most receive no treatment.

When support is available, women are often directed towards talking therapies such as cognitive behavioural therapy, or CBT, and mindfulness.

CBT is a structured talking therapy that helps people identify and change patterns of thought and behaviour affecting their mental health.

The review examined 115 clinical trials involving more than 12,000 participants across 30 countries.

It found that yoga, massage, omega-3 supplements and bright light therapy were broadly as effective as talking therapies at reducing depression symptoms during pregnancy.

Bright light therapy involves controlled exposure to bright light and is sometimes used to treat mood conditions.

The findings point to the importance of social support and increased connection, as all these approaches offer some element of contact or guided support.

Led by King’s College London, the research brought together trial evidence across every type and format of treatment for antenatal depression under a common framework.

Antenatal depression is depression that occurs during pregnancy.

The study was conducted as part of HappyMums, a European consortium led by the University of Milan that aims to improve mental health support during pregnancy and after birth.

Carmine Pariante, professor of biological psychiatry, said: “This is the most comprehensive analysis of treatments for depression in pregnancy ever conducted, and the findings should prompt a rethink of how we support women during this critical period.

“The evidence is clear that there is no single best approach. What matters is that women have access to a range of options, and that clinicians feel equipped to offer them.”

The researchers said yoga and omega-3 supplements could be legitimate treatment options, rather than stopgaps, for women on waiting lists or those who struggle to access mental health support.

However, the studies differed considerably in design, sample size and how results were measured, so the findings should be interpreted with care.

The team said non-psychological approaches could help women cope with long waits for care without ruling out other treatments alongside them.

Digital and online interventions, including apps and telephone-based support, were also found to be as effective as face-to-face treatment.

Researchers said this could affect how antenatal depression is managed, particularly for women who cannot travel or face long waits for in-person care.

The team found no randomised controlled trials of pharmaceutical treatments for antenatal depression, despite antidepressants being widely prescribed for depression outside pregnancy.

A randomised controlled trial is a study in which participants are randomly assigned to different treatment groups, allowing researchers to compare outcomes more fairly.

Evidence for drug treatment during pregnancy therefore relies on indirect research rather than trials carried out during pregnancy, reflecting long-standing caution around testing medicines in pregnant populations.

NICE guidelines recommend antidepressants for moderate to severe depression in pregnancy, while evidence from outside formal pregnancy trials suggests they can be safe and effective.

However, the researchers said trials are still needed, particularly for women who cannot access or engage with other forms of support.

Riddhi Laijawala, trial manager and PhD student, said: “Depression in pregnancy is common, but it is not inevitable, and it is treatable. What this review shows is that the options available to women are broader than many people realise.

“A yoga class, music therapy, or an online programme may not sound like clinical treatment, but the evidence suggests they can make a real difference, and for many women they may be easier (and quicker) to access than a course of therapy.”

Depression during pregnancy affects an estimated 28.5 per cent of pregnant people worldwide, but only around one in five receives appropriate and timely treatment.

The team said closing this treatment gap should be a priority for health systems because the condition can affect both parent and child.

The HappyMums project is supported by the European Union’s Horizon Europe research and innovation programme.

Type 2 diabetes rising among young women, experts warn

Published

on

Type 2 diabetes is rising among women in their 20s in England, with experts warning of a worrying increase since the Covid pandemic.

The rise has largely occurred since the pandemic and is closely linked to increasing obesity levels, according to an analysis of NHS data from 2011 to 2024.

The condition is serious and can lead to severe complications, including heart attacks and strokes.

Diabetes UK said it tends to be more aggressive when it develops at a younger age, raising the risk of serious complications and shorter lives.

The charity said early diagnosis is vital for people at risk to help prevent long-term organ damage.

The condition can sometimes be put into remission through healthy eating and maintaining a healthy weight, without relying on glucose-lowering medicines.

Researchers said newer obesity treatments, including GLP-1 injections and pills, may also help alongside healthy eating advice.

About 90 per cent of the six million people living with diabetes in the UK have type 2 rather than type 1, or insulin-dependent, diabetes.

The risk increases with age, and older adults still account for the largest proportion of new diagnoses.

However, NHS England estimates suggest that 12,000 people under 30 are now living with the condition, with women making up more of the younger cases.

Common symptoms include feeling very tired, urinating more often than usual and feeling thirsty all the time.

Researchers at Imperial College London analysed NHS data from the English National Diabetes Audit to examine trends over time.

The figures showed that cases are falling slightly among older adults, who still account for the largest share of new diagnoses.

However, diagnoses are increasing rapidly among people under 40, with some of the sharpest rises among women aged 20 to 29.

Body mass index at diagnosis has also been rising more quickly among younger adults than in older age groups, pointing to obesity as a likely factor.

Body mass index, or BMI, is a measure of obesity based on a person’s height and weight.

Separate NHS data for England shows obesity rates have worsened since the pandemic, with nearly one in three people now affected.

The largest increases over time have been among younger adults.

Between 2019 and 2025, new obesity cases rose by 16 per cent among people aged 20 to 29 and by almost 20 per cent among those aged 30 to 39.

Rates fell among adults aged 60 to 79 over the same period.

Lead researcher Dr Shivani Misra said: “We think that the earlier onset of severe obesity in young people is increasing their type 2 diabetes risk in early life and pulling down their age at diagnosis.

“This is really worrying given the poor health outcomes from early-onset type 2 diabetes.”

Misra said much of the discussion about rising rates among younger people had focused on ethnic minority groups, which have traditionally been considered at higher risk.

However, the new data suggests the trend extends well beyond those communities.

She added: “We now see that incidence is also increasing in white populations too, showing that this public health challenge is broadening across the generations.”

Diabetes UK said better follow-up care is also needed for mums-to-be diagnosed with gestational diabetes during pregnancy because it raises the risk of developing type 2 diabetes after childbirth.

Some studies have suggested that the risk of developing the condition may also increase after being ill with Covid, although the evidence remains inconclusive.

AstraZeneca drug approved for breast cancer in EU

Published

on

AstraZeneca’s breast cancer drug Etcamah has been approved in the EU as part of a combination treatment for advanced disease.

The European Commission acted on a positive opinion from the Committee for Medicinal Products for Human Use, the Cambridge, England-based drug maker said.

The decision followed positive results from the Serena-6 phase III trial, which showed a 56 per cent reduction in the risk of disease progression in advanced oestrogen receptor-positive breast cancer.

A phase III trial is a large, late-stage study used to assess a treatment’s safety and effectiveness before wider regulatory approval.

Oestrogen receptor-positive breast cancer is a form of the disease that can grow in response to the hormone oestrogen.

Etcamah, whose generic name is camizestrant, was tested in combination with a cyclin-dependent kinase 4/6 inhibitor.

Known as CDK4/6 inhibitors, these medicines block proteins that help cancer cells grow and divide.

AstraZeneca said the Etcamah combination has also been approved in Japan, the UAE and Saudi Arabia based on the Serena-6 trial results.

The company said breast cancer remains the leading cause of cancer death among women in Europe, with more than 140,000 deaths and more than 540,000 patients diagnosed in 2024.

AstraZeneca shares were down 0.6 per cent at 12,628 pence in London on Thursday.
