AI smart T-shirt from Imperial College London could spot hidden inherited heart rhythm disorders
Researchers at Imperial College London have developed an AI-assisted smart T-shirt that records continuous ECG-style signals with fabric-woven sensors to detect intermittent inherited heart rhythm disorders outside hospitals, aiming to prevent sudden cardiac death through extended, comfortable monitoring.
- Continuous, comfortable monitoring: Up to 50 woven sensors in a washable T-shirt record ECG-style signals for days or weeks.
- AI analysis: Algorithms trained on ECGs from more than 1,000 people search long recordings for patterns linked to conditions such as Brugada syndrome.
- Feasibility trial: About 200 volunteers will wear the shirt for up to three months; clinical use could follow in roughly five years if trials and approvals proceed.
- Funding and support: Project backed by the British Heart Foundation and NIHR Imperial Biomedical Research Centre with >£340,000 initial funding.
How the AI smart T-shirt heart monitoring system works
The device looks like a soft sports T-shirt: no wires or sticky pads. Instead, up to 50 ECG-style sensors are woven into the fabric in positions that mimic conventional ECG leads. The garment can be worn under clothing, slept in, and washed like ordinary sportswear. It records the heart’s electrical signals continuously for days or weeks, and AI sifts through long records to flag small or brief changes that may indicate inherited rhythm disorders. See the Imperial College London release for details.
Why longer monitoring matters
A standard hospital ECG lasts about 10 minutes, and typical portable monitors record for 24–48 hours with adhesive electrodes that must be removed for showering. Those short snapshots can miss intermittent problems: many inherited rhythm disorders are episodic and may be absent during a brief clinic ECG. When clinicians can review days or weeks of data, rare events and abnormal trends become easier to detect, giving doctors better opportunities to act earlier. Imperial’s news item outlines this rationale in depth: Imperial news.
The technology and the AI
The shirt’s design is based on sportswear engineering: soft fabric conceals dozens of sensors placed to capture reliable signals even when the wearer moves. Some versions can record continuously for up to a week, and trial garments will be evaluated for longer durations. Sensor data feed AI models trained on mixed datasets—including recordings from patients with inherited rhythm disorders and healthy volunteers—so the system can learn to separate harmless variation from signals that suggest elevated risk. More on the approach is available from the Imperial College London release and the British Heart Foundation summary.
Study plan, funding and oversight
The project received more than £340,000 in funding from the British Heart Foundation. An initial feasibility study will recruit about 200 volunteers through Hammersmith Hospital’s Peart-Rose Research Unit; participants will wear the shirt for up to three months so researchers can test detection of abnormal rhythms in everyday life. The work is supported by the NIHR Imperial Biomedical Research Centre. See the team’s description at Imperial College London and the funding note at the British Heart Foundation.
Professor Zachary Whinnett, of the National Heart and Lung Institute, said: “Far too many people die from inherited heart conditions which could be treated if identified earlier… Our AI-assisted t-shirt will provide a practical and comfortable solution for longer-term scanning.”
Who could benefit
Inherited heart rhythm disorders affect people of all ages. Imperial researchers estimate about 340,000 people in the UK carry conditions that raise their risk of dangerous rhythms and sudden cardiac death. The British Heart Foundation highlights links between inherited conditions and symptoms such as breathlessness and fainting, and estimates around 12 young lives under 35 are lost each week in the UK to such causes. Compared with short ECGs, long-term wearable monitoring could help families and clinicians find problems earlier and offer treatments or lifestyle changes to reduce risk.

What still needs to be proven
The smart T-shirt remains experimental. Key questions include:
- How well the AI performs across varied populations (age, skin type, activity levels).
- Comfort and reliability of the garment for prolonged wear and repeated washing.
- False alarm rates and pathways for clinical follow-up.
- Regulatory review of durability, data security, and demonstrated clinical benefit.
Broader testing is planned to answer these points; see reporting from Medical Xpress.
Implications for Sonoma, California
Economic impact: Local clinics and wearables companies in Sonoma could find new business opportunities if the AI smart T-shirt reaches the U.S. market. Medical device suppliers, telemedicine providers, and labs might partner with health systems to offer long-term monitoring services, shifting some testing into outpatient or home settings.
Political and regulatory consequences: U.S. regulators such as the FDA will require trial evidence and safety data before approving wearables for clinical diagnosis. Sonoma health leaders and lawmakers may need to address access, insurance coverage (Medicare, Medi-Cal, private insurers), data privacy, and health equity debates.
Social and cultural effects: Families with histories of heart disease may welcome a less invasive way to monitor relatives. Sonoma’s active lifestyle fits a washable, unobtrusive T-shirt better than wired monitors. However, residents should understand the shirt is a screening tool; positive findings require cardiology follow-up.
Practical applications: Local doctors could use long-term wearable data to detect intermittent rhythm problems in patients with fainting, unexplained symptoms, or family histories of sudden cardiac death. Clinics should prepare protocols for remote monitoring data, referrals, and questions about cost and data handling.
