Introduction to S-type tension and pressure sensor

Characteristics of type I tension pressure sensor: (1) Linearity: refers to the degree that the actual relationship curve between the sensor output and input deviates from the fitting straight line. It is defined as the ratio of the maximum deviation value between the actual characteristic curve and the fitting straight line within the full range to the full range output value.

New sensor can accurately "read" human micro-expression

According to Maims Consulting, the Liang Jiajie research team of Nankai University successfully solved the contradiction between high sensitivity and large working deformation in the stress sensor 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 human body.
