P‐15.21: High sensitive Under‐Screen Piezoelectric sensor Integrated with OLED display Module

In this paper, a self‐powered piezoelectric sensor is developed for pressure monitoring. Though molecular design and processing optimum of piezoelectric materials, the the accuracy of pressure sensing was significantly improved, and the sphygmic signal of the human body can be detected. In particular, the prepared sensor is capable to be integrated under flexible OLED display to realize sphygmic signal detection. Thus, a new under‐screen flexible OLED health sensing device is realized.
