With the increasing demand for intelligent prosthetics, intelligent perception and human-computer interaction, flexible pressure sensors have rapidly developed as the core device of wearable electronic devices. However, flexible pressure sensor with high sensitivity, wide detection range and low cost is still a challenge. In this work, we reported the carbon-based flexible pressure sensor enabled by multigradient architectures with a high sensitivity of 6.83 kPa−1 at low pressure and 0.72 kPa−1 at high pressure. Besides, the minimum detection limit of the sensor can achieve 4 Pa. We made an intelligent glove with five sensors to detect the pulse of human body and the signal changes when grasping different objects. These applications indicate great potential of the intelligent glove in pulse diagnosis and object recognition fields.

摘要

With the increasing demand for intelligent prosthetics, intelligent perception and human-computer interaction, flexible pressure sensors have rapidly developed as the core device of wearable electronic devices. However, flexible pressure sensor with high sensitivity, wide detection range and low cost is still a challenge. In this work, we reported the carbon-based flexible pressure sensor enabled by multigradient architectures with a high sensitivity of 6.83 kPa−1 at low pressure and 0.72 kPa−1 at high pressure. Besides, the minimum detection limit of the sensor can achieve 4 Pa. We made an intelligent glove with five sensors to detect the pulse of human body and the signal changes when grasping different objects. These applications indicate great potential of the intelligent glove in pulse diagnosis and object recognition fields.
