OsteoSense — preventive bone health, at home

Bone health insight, tracked at home.

OsteoSense is being developed as a reusable, non-invasive device designed to help you notice changes in bone health early — regularly, from home, instead of waiting years between scans. It's currently under development and undergoing validation.

Who it's for

Not just a question of age.

Bone density is shaped by hormones, training load, diet, and genetics — often years before it shows up on a scan. A few groups face a higher chance of it happening quietly.

The problem

Bone loss often has no warning signs — until a fracture happens.

Most people only find out their bones have weakened after a fracture. There's no discomfort along the way, no early warning built into how the condition normally gets caught.

1 in 3

women over 50 will experience an osteoporosis-related fracture in their lifetime.

1 in 5

men over 50 face the same risk, and are less often offered screening for it.

Silent

Bone loss is typically painless and symptom-free until a fracture occurs.

A single scan is a snapshot, taken years apart. OsteoSense is being designed for the opposite: an ongoing trend, tracked from home, so a change has a chance of being noticed while there's still time to act.

01 — Use

A reusable, non-invasive device

OsteoSense is designed to be worn briefly at home to take a reading — no needles, no lab visit, nothing single-use.

02 — Answer

A short, honest check-in

A few minutes answering a questionnaire built around established clinical risk factors, done from home, on your schedule.

03 — Know

A clear, personal score

Get a bone health score and plain-language next steps — not a wall of numbers to decode alone.

The product

OsteoSense — regular insight, not a single snapshot.

A reusable, non-invasive at-home device, designed to follow the signals behind bone health over time — built to give a change more chance of being noticed while there's still time to act on it.

Every reading is placed against your own history and against established clinical risk factors, so the score is designed to mean something — not just a number that moves.

＋ One reusable device — nothing single-use, nothing to replace
＋ Regular trend, not an occasional scan
＋ Plain-language guidance you can act on at home
＋ Flags what's worth raising with a clinician

What we are

A preventive health company, built around real risk.

Persis Health Innovation is redefining preventive healthcare for women. Many of the chronic conditions that most affect women's lives develop quietly, and differently in women, often years or decades before symptoms appear. Yet healthcare systems remain largely reactive, intervening only once those conditions are well established and the opportunity for prevention has passed.

We exist to close that gap. Our first product, OsteoSense, is a reusable, non-invasive at-home device designed to help people track bone health regularly rather than waiting for a single scan years apart.

Addressing the gap

Routine monitoring of the markers that quietly shape long-term health.

Our platform addresses a significant gap in women's and children's health: a non-invasive biosensor for routine monitoring of key nutritional biomarkers, starting with vitamin D and iron.

Deficiencies in these nutrients are common among women — particularly during pregnancy, lactation, and menopause — and among children, contributing to anaemia, osteoporosis, fatigue, and a raised risk of long-term chronic disease.

Solving the problem

Painless, accessible testing — designed for the people it usually fails.

Our saliva-based biosensors are designed to be painless, accessible, and accurate, aimed squarely at the groups invasive testing serves worst: pregnant women, children, and the elderly.

A convenient alternative to blood tests reduces the burden on healthcare systems, cuts the risk that comes with supplementing blind, and supports genuinely preventative care. Scalable, affordable technology is what makes that reach everyone rather than a few.

Where things stand

＋

Today

We're developing OsteoSense and building our approach to bone health scoring, grounded in established clinical risk factors.

＋

In development

Wearable integration, the companion app, and the underlying scoring model are being built and refined.

＋

Being validated

The accuracy of our scoring approach is still being tested — we'll be upfront about results as that work progresses.

Who's behind it

A team built across science, product, and business.

Persis Health is led by a technical lead in biosensing, working alongside a project management team with hands-on business expertise, an AI and software development group, and dedicated business advisors — backed by an electronics and biosensing advisory board from Imperial College London, supported by ORUK.

Who's at risk

Bone density doesn't wait for a birthday.

It moves in response to what's happening in the body — growth, pregnancy, training load, diet, hormones, genetics. Some of these are life stages everyone passes through; others depend on how someone lives, trains, or eats. Recognising your own risk window is the first step.

Growth Pregnancy Heavy training Restrictive diet Perimenopause Menopause & aging

Hormonal change

Perimenopause & menopause

Falling oestrogen speeds up bone loss, often years before other symptoms make it obvious. This is the single biggest risk window for most women — but it's a hormonal shift, not an inevitability to just wait out.

Training load

Athletes & heavy exercisers

Intense training without enough fuel or recovery — sometimes called RED-S — can quietly reduce bone density regardless of age or gender, especially in endurance and weight-conscious sports.

Diet

Plant-based & restrictive eating

Cutting out food groups without planning around calcium, vitamin D, protein, or B12 raises risk over time — whether the restriction is a personal choice, a medical need, or disordered eating.

Genetics & age

Family history & aging

A parent's fracture history and age remain two of the most established risk factors on their own — and they compound with any of the stages above.

Our mission

Prevention should start earlier.

Bone density can change quietly at several points across life — growth, pregnancy, heavy training, restrictive eating, and hormonal change all play a part. Hormonal shifts like perimenopause and menopause are one of the most significant risk windows, but far from the only one. Most people only find out something changed after a fracture, at which point the conversation is about treatment, not prevention. We think that conversation should start much earlier, for anyone at risk.

Vision & mission

＋

Our vision

To redefine preventive care, making proactive, data-driven health data accessible to all — regardless of gender, geography, or clinical status.

＋

Our mission

To empower individuals and clinicians with non-invasive, intelligent tools that enable early detection and prevention of disease, long before symptoms appear.

Reducing treatment costs and improving outcomes through AI-enabled, personalised preventive monitoring that anticipates health needs before they arise.

What we believe

＋

Prevention over late diagnosis

Waiting for a scan to explain what already happened isn't good enough. We're building toward tools designed to help notice change while there's still time to act.

＋

Insight you can act on

A number on its own doesn't help anyone. Every reading is meant to come with plain-language context and a next step.

＋

Built around real risk, not just age

Bone health has historically been framed as an older woman's issue. We're designing OsteoSense around the fuller picture — hormonal change, training, diet, and genetics.

＋

Trust before claims

We're upfront about what OsteoSense can do today, what's still being developed, and what's still being validated.
