Abstract: Flexible pressure sensors are the basic building blocks for implementing electronic or tactile skin for robotics, wearable electronic and human-machine interactions. To achieve these potential applications, subtle pressure detection is required under a variety of conditions and is often limited by low sensitivity. Herein, we report an oxidized Ti3C2T (x) film with outstanding mechanical flexibility via vacuum filtration to assemble a novel flexible pressure sensor. Benefiting from the large deformation of the composite films, the prepared pressure sensor exhibits low detection limits of 8 Pa and fast response/recovery time of 70/20 ms, in addition to excellent cycling stability (10 000 cycles). These novel functions allow us to act as electronic skin to monitor human physiological activity in a personalized manner. Obviously, this good sensing characteristic can highlight the broad prospects of oxidized MXene-based pressure sensors for higher integration of flexible electronic devices.
