Your next heart test may be a T‑shirt: Imperial College’s AI smart T‑shirt aims to find hidden inherited heart rhythm disorders
Imperial College researchers are developing an AI‑powered smart T‑shirt with up to 50 ECG sensors woven into fabric to provide comfortable, continuous heart monitoring during daily life, aiming to detect inherited rhythm disorders often missed by short hospital ECGs.
- Continuous, wearable ECG: A washable sport‑style T‑shirt with up to 50 sensors captures ECG‑style signals without sticky pads.
- AI trained on real data: Algorithms learned from ECG records of more than 1,000 people to distinguish harmless variation from dangerous signs.
- Funded Feasibility Study: >£340,000 from the British Heart Foundation and NIHR Imperial BRC support; ~200 volunteers planned for up to three months.
- Clinical timeline: Researchers estimate possible availability in roughly five years, pending trials and regulatory approval.
How the AI smart T‑shirt works
The hardware: The garment resembles sportswear. Up to 50 ECG‑style sensors are woven into soft fabric so sensors sit close to the skin without adhesive pads. Small electronics capture signals for storage or transmission, and the shirt is designed to be worn under clothing, slept in and washed.
The software: Artificial intelligence analyses long stretches of ECG‑style data to detect subtle or intermittent patterns humans may miss. The team trained the model on ECG records from more than 1,000 people, including those with known inherited rhythm disorders and those without, to teach the system to tell normal variation from dangerous signs. See the Imperial College research notes: Imperial College (project article) and Imperial College (summary).
Professor Zachary Whinnett: “Far too many people die from inherited heart conditions which could be treated if they were identified earlier… We hope our AI‑assisted t‑shirt will provide a practical and comfortable solution, allowing us to carry out longer‑term scanning that could improve diagnosis.”
Why short ECG checks can miss dangerous conditions
Standard clinic ECGs give a short snapshot of the heart’s electrical activity. For many problems that is sufficient, but inherited heart rhythm disorders can be intermittent—appearing for minutes or hours and then disappearing. If a standard ECG is taken during a calm phase, it may look normal.
Current home monitors use adhesive electrodes and a waist‑worn box; they work but are bulky, require careful placement, and often must be removed for showering, limiting long‑term use. The smart T‑shirt aims to reduce those barriers and enable days or weeks of recording in daily life.
Study design and early testing
Funding and development: The project received more than £340,000 from the British Heart Foundation and support from the NIHR Imperial Biomedical Research Centre to build prototypes and train the AI.
Feasibility study: Researchers plan a study at Hammersmith Hospital’s Peart‑Rose Research Unit with about 200 participants wearing the shirt for up to three months to test performance in everyday life. The team will monitor technical signal quality, false alarms, missed events and user comfort.
- Prototype development and AI training using >1,000 ECG records.
- ~200 volunteers, up to 3 months’ wear to evaluate real‑world detection.
- If reliable, possible adaptation for children or common rhythm problems such as atrial fibrillation, subject to further testing and regulatory approval.
What the research still needs to prove
Key unanswered questions include:
- Can the shirt collect clean ECG signals during heavy movement or sweating?
- How will long‑term data storage, privacy and consent be handled?
- Will AI performance be consistent across body types, skin tones and ages?
- Will participants wear the device as instructed for the required periods?
Researchers will assess technical performance and participant experience in the feasibility study and prepare for independent regulatory review before clinical prescription.
Voices and broader support
British Heart Foundation: Professor James Leiper said: “This innovative research will leverage the power of AI to help clinicians unmask these hidden conditions and identify patients at risk of sudden death.” The BHF emphasises that projects like this could help reduce young deaths linked to inherited heart disease (BHF).
Outside reporting has highlighted the approach’s potential while urging careful testing and oversight — for example, coverage by Fox News.
Implications for The Imperial Valley
Economic: In largely rural regions with fewer specialty clinics, a wearable monitor could extend cardiology services without long patient travel, reduce emergency care rates and lower financial burdens related to specialist travel.
Political and policy: Local health officials may view the technology as a tool to address specialty care gaps; adoption discussions will raise questions about coverage, consent and funding.
Social and cultural: For residents working long, physically demanding hours, a washable wearable that behaves like regular clothing could be easier to use than wired systems. Clear, bilingual community education and trusted local health workers will be key to building acceptance.
Practical applications: Clinicians could prescribe extended home monitoring instead of waiting for rare events during a clinic ECG. Pilot partnerships could test performance across climates and work environments common in the Imperial Valley.
What to watch next
Follow the feasibility study results and any US‑based trials. If accuracy and affordability are demonstrated, the shirt could be integrated into outreach programs serving rural and working communities. For now, careful testing, privacy protections and regulatory clearance are essential prerequisites.
