Information
According to Mymes Consulting, Liang Kaijie's group at Nankai University successfully solved the contradiction between high sensitivity and large work deformation in stress sensors for the first time by using the synergistic effect of three low-dimensional nanomaterials. This research has greatly improved the performance of stress sensor devices such as wearable devices, and can accurately capture the subtle expression changes of the human body.
Liang Jiajie's group used the synergistic effect of various nano-functional materials such as fullerene, metallic silver nanowires, and graphene oxide to improve the flexibility of the host material by introducing a guest material with a low coefficient of friction into a rigid host material with a layered structure. It solves the problems that have long plagued the academic community. The sensor made of this material can maintain extremely high response sensitivity in a large working deformation range. The research team wears the new wearable stress sensor in different parts of the human body for monitoring the full range of human movements, and can clearly capture the tiny skin movement changes caused by pulse beats on the human wrist; and 3 This characteristic peak is clearly displayed; when worn on the neck and throat, you can clearly detect the vocal cords of the human body and recognize different syllable changes.
According to another introduction, this new type of stress sensor can be printed and formed in one step by printing. It has the advantages of good repeatability and simple preparation process, which can provide a good material foundation for real productization. At present, the research group is actively docking and coordinating to promote the application of the stress sensor in wearable devices related to human motion detection and human health monitoring. Related results were published in the latest issue of Advanced Functional Materials.

First, the classification of the working principle of sensors Physical sensors use physical effects, such as piezoelectric effects, magnetostrictive phenomena, ionization, polarization, thermoelectric, photoelectric, and magnetoelectric effects. Small changes in the measured signal quantity are converted into electrical signals.
