Screen-Printed All-in-One Pressure Sensor With Integrated Microsupercapacitor

Flexible multifunctional all-in-one devices are an effective strategy to realize smaller and lighter wearable devices. Herein, a screen-printing paste is successfully made from mass-produced laser-induced graphene (LIG) powder and then utilized for screen printing various LIG-patterned electrodes, subsequently creatively assembled into a novel all-in-one pressure sensor with integrated microsupercapacitor. The as-assembled all-in-one device not only has high sensitivity, fast response/recovery time, ultralow detection limit, good stability, and excellent ability to accurately monitor various human activities but also has high area specific capacitance and good mechanical flexibility. This fresh screen-printed multifunctional all-in-one pressure sensor with integrated microsupercapacitor opens up a new avenue for the development of future flexible wearable products.
