There is a clinical need for the development of sensors to measure the buildup of pressure on organs, as it is indicative of many underlying ailments. However, electronic devices must be flexible and have low Young’s modulus to be compatible with human tissues. Although many advances have been made in bioresorbable devices making these devices with safe materials and simple processes remains challenging. Here, we propose a simple and scalable method of fabricating biocompatible and bioresorbable piezoelectric poly-l-lactide acid (PLLA) based films. Films that will be used to fabricate force sensors. Our strategy focuses on material processing to improve the crystallinity and orientation of polymer chains to achieve a good piezoelectric response.
