Abstract
Flexible pressure sensors and electronic skins have attracted more and more attention in human–machine interaction, intelligent robotics, and wearable health monitoring electronics. However, it is still challenging to trade off between high sensitivity and a wide working range to meet a variety of pressure applications. Herein, we reported a flexible pressure sensor assembled by a simple and cost-effective approach using coating Ti3C2T

quantum dots on leaf veins. Due to the ultrahigh specific surface area, excellent electrical conductivity, and hierarchical micro-network structure, the device shows excellent sensitivity (25.83 kPa−1), a wide working range (0.1–1500 kPa), remarkable high-pressure resolution (5 kPa under high pressure of 100 kPa or 5%), high stability (over 4000 cycles) and fast response time (<0.3 s). Furthermore, we demonstrated the applications of body motion monitoring during different parts and activities. The results prove our device is a potential candidate for next-generation wearable electronics and human–machine interaction.
