Force Sensor Array

Abstract

This invention discloses a force sensor array, characterized in that it comprises: a circuit board, a plurality of gas pressure sensors arranged on the circuit board, and an energy-absorbing film layer covering the gas nozzle of each gas pressure sensor; the said energy-absorbing film layer has a certain elastic deformability, and can convert impact kinetic energy into heat energy. Through the provision of the energy-absorbing film layer, circuit board and other structures, when pressure is applied slowly, the energy-absorbing film layer of this invention shows the characteristics of solid to transfer pressure; different gas pressure sensors sense different pressure values during stress. The circuit board collects the pressure values fed back by the gas pressure sensors to show the spatial distribution of stress. When impact bursting force is applied to the energy-absorbing film layer, the energy-absorbing film layer converts kinetic energy into heat energy for dissipation, which can buffer impact and absorb more than 95% of the impact energy to improve the bursting resistance of the entire array. In addition, it is cost-effective.
