Paper Abstract

Measuring vital physiological pressures is important for monitoring health status, preventing the buildup of dangerous internal forces in impaired organs, and enabling novel approaches of using mechanical stimulation for tissue regeneration. Pressure sensors are often required to be implanted and directly integrated with native soft biological systems. Therefore, the devices should be flexible and at the same time, biodegradable, to avoid invasive removal surgery that can damage directly-interfaced tissues. Despite recent achievements in degradable electronic devices, there is still a tremendous need to develop a force sensor which only relies on safe medical materials and requires no complex fabrication process to provide accurate information on important bio-physiological forces. Here, we present a new strategy for material processing, electromechanical analysis, device fabrication, and assessment of a new piezoelectric Poly-L-lactide (PLLA) polymer to create a biodegradable, biocompatible piezoelectric force-sensor which only employs medical materials used commonly in FDA-approved implants, for the monitoring of biological forces
