DuPont collaborates with STMicroelectronics

New smart wearable device concept for monitoring biosignals.

DuPont Liveo Healthcare Solutions is collaborating with STMicroelectronics to develop a new smart wearable device concept for remote biosignal-monitoring.

The DuPont Liveo Smart Biosensing Patch concept supports the development of biosignal-monitoring devices with stable data quality and high patient comfort.

"Dedicated Liveo research teams collaborate with suppliers and manufacturers worldwide to create solutions across a vast array of medical applications – including smart devices that can share data between patients and doctors," said DuPont Liveo Global Business Leader Eugenio Toccalino. "The wearable device concept that resulted from the collaboration between DuPont and ST is the DuPont Liveo Smart Biosensing Patch prototype, which employs multifunctional microsensors and control electronics from ST embedded in a flexible patch design from DuPont."

By collaborating with others across the healthcare ecosystem – from technology developers and material suppliers to device fabricators and OEMs – DuPont is developing more patient-centric solutions that contribute to better patient outcomes.

"ST designed the electronics and sensors for the smart skin patch prototype using our accelerometer and vertical analog front end next-generation sensors with in-sensor AI, a microcontroller with Bluetooth module, ultra-low-power-management units, firmware, and algorithm support to create a flexible board design capable to analyze electrical and mechanical heart activity in full synchronization to extract multiple vital signs," said Simone Ferri, STMicroelectronics AMS Group Vice-President and MEMS sub-group General Manager. "The performance of ST's electronic sensors is enhanced by the conformability and conductivity of the DuPont™ Liveo™ materials used to create the patch."

Through this collaboration, DuPont brings a broad range of medical patch technologies, including DuPont Liveo Soft Skin Conductive Tape 1-3150 – a silicone-based thermoset adhesive for sensing and transferring electrical biosignals, and Liveo Soft Skin Adhesives.

ST's sensor and embedded development technology and semiconductor manufacturing expertise, combined with the key benefits of silicone technology with electrically conductive properties allow Liveo Soft Skin Conductive Tape technology to be used as a skin electrode for biosignal-monitoring applications where good skin conformability, no drying over time, and repositionability with gentle adhesion and atraumatic removal is vital. It can be used in single electrodes for short-term monitoring, as well as in medical wearable patches for long-term monitoring lasting seven or more days.

DuPont also designed the layout for the Liveo™ Smart Biosensing Patch and supplied rapid prototyping capabilities.

The result of this collaboration is not just a single prototype, but a robust ST-empowered Liveo Smart Biosensing Patch technology toolbox for remote ECG and SCG monitoring.

The DuPont and ST integrated patch technology is designed to improve people's lives, making it easier to use than typical rigid box designs. It's smaller, lighter, and more comfortable and can be worn longer. Plus, the sensors are multifunctional, intelligent, and adaptable, and the data provided is extremely stable.
