If you are a digital health company looking to reduce hospital readmissions for chronic patients — this project developed a fully integrated mHealth platform with biosensors for breath and saliva biomarkers, ECG, blood pressure, and activity monitoring, all connected to a cloud-based knowledge management system. The platform was technically tested with 14 consortium partners across 6 countries. It could give your product a proven sensor-to-cloud pipeline for medication adherence monitoring.
Smart Sensors and App That Keep Heart Failure Patients on Track with Their Treatment
Imagine someone with heart failure has to juggle pills, diet, exercise, and doctor visits every single day — and one slip-up could land them back in the hospital. HEARTEN built tiny sensors that fit into a smartphone and even a drinking cup to check whether a patient is actually taking their medication, just from their breath and saliva. All that data — plus heart readings, blood pressure, and activity tracking — feeds into a cloud system that alerts doctors and caregivers before things go wrong. Think of it as a safety net that catches problems early, so patients stay home instead of back in the ER.
What needed solving
Heart failure patients frequently end up back in the hospital because they don't stick to their medication, diet, and exercise plans — and doctors only find out when it's already an emergency. Current monitoring is fragmented: patients self-report (unreliably), wearables track only basic vitals, and there's no single system connecting doctors, caregivers, nutritionists, and insurers around one patient. The result is billions in avoidable readmission costs and poor patient outcomes.
What was built
HEARTEN built a complete mHealth platform consisting of: (1) breath biosensors integrated into smartphones and saliva biosensors integrated into drinking cups that detect heart failure biomarkers and verify drug adherence; (2) a sensor kit covering ECG, blood pressure, physical activity, and weight; (3) a cloud-based knowledge management system that aggregates all patient data and delivers alerts; and (4) a cooperative interface for patients, doctors, caregivers, nutritionists, and fitness experts. The final integrated platform (D8.2) was technically tested and quality-assured.
Who needs this
Who can put this to work
If you are a medical device manufacturer seeking next-generation biomarker detection — this project developed breath biosensors integrated into smartphones and saliva biosensors embedded in everyday objects like drinking cups. These detect heart failure biomarkers and verify drug adherence without invasive testing. With 8 industry partners already involved in development, the technology has a clear path toward commercial sensor products.
If you are a health insurer or hospital network dealing with costly heart failure readmissions — this project built a cooperative environment where healthcare professionals, caregivers, nutritionists, and fitness experts all share one patient dashboard. The system issues warnings and coordinates interventions before emergencies happen. With EUR 4,589,507 in EU research funding already invested, the core platform and clinical validation work has been done.
Quick answers
What would it cost to license or adopt this technology?
The project was funded with EUR 4,589,507 in EU contributions across 14 partners. Licensing terms would need to be negotiated directly with the consortium, led by Université Lyon 1. Based on available project data, no public pricing model has been disclosed.
Can this scale to large patient populations?
The platform was built on cloud architecture specifically designed to collect multiparametric data from multiple sensor types (breath, saliva, ECG, blood pressure, activity, weight, nutrition). The system supports multiple user roles — patients, doctors, caregivers, nutritionists, fitness experts, and insurers. Scaling would depend on cloud infrastructure capacity and regulatory clearance in target markets.
Who owns the intellectual property?
IP is distributed among the 14 consortium partners from 6 countries (DE, EL, ES, FR, IT, PT), coordinated by Université Lyon 1 in France. With 8 industry partners and 5 SMEs in the consortium, commercial licensing arrangements likely exist. Specific IP terms would need to be discussed with the coordinator.
Does this meet medical device regulations?
The project delivered a technically tested and quality-assured integrated platform (D8.2). However, full medical device certification (e.g., CE marking under MDR) status is not confirmed in the available deliverable data. Any commercial deployment would require regulatory clearance for the biosensor components.
How long would integration take?
The project ran from 2015 to 2018 and produced 12 deliverables including the final integrated platform. The modular architecture — separate sensor kit, smartphone app, and cloud backend — suggests components could be integrated individually. Based on available project data, a phased integration approach would be most practical.
What clinical evidence supports this?
The project targeted patients with chronic and acute heart failure, including post-ischemic and dilated cardiomyopathy cases requiring hospital readmission. The final deliverable (D8.2) includes evaluation of technical testing of the integrated platform. Specific clinical outcome data would need to be requested from the consortium.
What happened after the project ended in 2018?
The project closed in March 2018. With 5 SMEs and 57% industry ratio in the consortium, there was strong commercial intent. Based on available project data, follow-up commercialization status should be verified directly with the coordinator at Université Lyon 1.
Who built it
The HEARTEN consortium is unusually strong on the commercial side: 8 out of 14 partners are from industry (57%), and 5 of those are SMEs — signaling real intent to bring results to market, not just publish papers. The consortium spans 6 countries (Germany, Greece, Spain, France, Italy, Portugal), giving it broad European market coverage. Coordination by Université Lyon 1 provides academic credibility, while the heavy industry presence means the technology was developed with real-world constraints in mind. For a business considering this technology, the existing industry network within the consortium could serve as a ready-made supply chain or partnership channel.
