  • Implantable, stretchable sensor for continuous biomechanical monitoring of the heart
    Patent number: 12618660
    Abstract: A modular approach for strain sensors for large deformations is provided. The strain sensor separates the extension and signal transduction mechanisms using a soft, elastomeric transmission and a high-sensitivity microelectromechanical system (MEMS) transducer. By separating the transmission and transduction, they can be optimized independently for application-specific mechanical and electrical performance. The durability of the strain sensor was evaluated by conducting cyclic loading tests over one million cycles, and the results show negligible drift. Applications of the strain sensor are suitable for human health monitoring as for example an implantable cardiac strain sensor for measuring global longitudinal strain (GLS).
