The device comprises a calibration stock, a piezoresistive strain sensor and a mobile terminal device, wherein the calibration stock comprises a mechanical arm and a control main board, the mechanical arm is connected with the control main board and executes an instruction of the control main board to knock on the piezoresistive strain sensor; and the piezoresistive strain sensor is arranged on the upper surface layer of the mobile terminal device, the mobile terminal device communicates with the control main board, the control main board receives an operation command from the mobile terminal, and operation of the mechanical arm of the stock is controlled.

Description

technical field [0001] The invention belongs to the technical field of sensors, in particular to a calibration device and method for a mobile terminal with piezoresistive sensors. Background technique [0002] The calibration of the traditional piezoresistive strain sensor is artificially pressed or not calibrated. [0003] The device and method for calibrating the piezoresistive strain sensor mobile terminal are greatly improved compared with the traditional manual random pressing or no calibration. Due to limited conditions, traditional piezoresistive strain sensors only perform simple calibration or no calibration, or the calibration method is too cumbersome to implement mass production. Especially for the piezoresistive strain sensor of the mobile terminal, the traditional piezoresistive strain sensor calibration method cannot meet the requirements of high precision, high stability, production line test calibration and other factors. [0004] For example, patent applic...
