Abstract
The invention discloses a graphene strain sensor array. The graphene strain sensor array comprises an array circuit board and array circuits arranged on the array circuit board, and the array circuit board is provided with a plurality of graphene strain sensing units connected with the array circuits; the graphene strain sensing units are used for converting collected signals into strain values by means of a signal collecting and processing system; each graphene strain sensing unit comprises two sensing films which are arranged crisscross, wherein each sensing film is formed by attaching a graphene layer and an elastic polymer layer, and electrodes are arranged at the two ends of each sensing film. According to the graphene strain sensor array with the structure, the transverse and longitudinal strain changes can be sensed simultaneously, the application range of the sensor array is greatly widened, and therefore a graphene strain sensor achieves more diversified development.
Description
technical field [0001] The invention relates to a graphene flexible sensor array. Background technique [0002] Wearable devices, electronic skin, and smart sensing are actively changing the way people perceive, think, and behave. Google Glass, iWatch, Electronic Tattoo, etc. provide people with a three-dimensional visual experience, expand the rich information dimension, and mine the health big data of the system. Wearable devices, electronic skin, and other sensor devices that can perceive external pressure, strain, temperature, airflow, and tactile signals like human skin. Due to its excellent characteristics, electronic skin is widely used in health monitoring, human-machine identification and so on. It can make robots feel tactile, and can cover the surface like clothes, allowing robots to perceive the orientation, shape, hardness and other information of objects. Nevertheless, people's constant pursuit of high-quality life, multi-resource acquisition, and new sensory...
