Description
technical field [0001] The invention relates to the field of electromechanical interaction, in particular to a dynamic or quasi-dynamic strength detection device and method. Background technique [0002] The main operations of electronic devices such as portable mobile phones and tablet computers that exist on the market are completed through touch screens. The touch screen is becoming more and more popular because of its ease of operation and lower and lower prices. The unique advantage of the touch screen is that it can help users achieve the same operation purpose without frequently moving the mouse and tapping the keyboard. The composition of the touch screen generally includes a touch panel, a touch response component, a touch control system, and a driver. The technical solutions mainly used in touch response components include resistive type, capacitive type, infrared type, surface acoustic wave type, etc. In addition to the limitations of self-generated technology, t...
