Abstract

The invention discloses a cobweb-like flexible tactile sensor capable of simultaneously detecting the magnitude and direction of force. The overall structure of the sensor is similar to a sandwich structure, a top electrode of the sensor is a flexible stretchable circular electrode, a bottom electrode of the sensor is a cobweb-like flexible stretchable electrode which serves as a stretching sensitive module and is prepared through a permeation-mold turnover process, and the middle of the sensor is three-dimensional tubular graphene sponge serving as a pressure sensitive module. The cobweb-likeflexible tactile sensor provided by the invention can effectively realize simultaneous high-sensitivity detection of the magnitude and direction of force.

Description

technical field [0001] The invention belongs to the fields of flexible electronics and wearable devices, new material technology and microelectronic systems, and specifically relates to a spider web-like flexible tactile sensor capable of simultaneously detecting the magnitude and direction of force. Background technique [0002] With the development of the information society and the continuous progress of the Internet of Things technology, the depth and breadth of people's collection of surrounding environmental information has been continuously improved. Traditional sensors may cause problems such as poor signal transmission quality due to their own rigidity. In contrast, flexible sensors can capture target analytes more efficiently and generate higher-quality signals due to their compatibility with arbitrary moving parts or curved surfaces. Flexible sensors have broad application prospects in the fields of robotics, biomedicine, wearable devices, implantable health dete...
