Embodiment Construction
[0026] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and implementation examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0027] In the present invention, the material of the pressure sensing layer is a transparent conductive oxide, such as indium tin oxide (Indium Tin Oxide, ITO) and other similar metal oxides. As the temperature rises, the resistance increases, and it is stretched and deformed by the pressing force. Afterwards, the resistance value decreases. The pressure sensing layer includes pressure sensing electrodes, and one pressure sensing electrode includes a plurality of pressure sensing electrode blocks.
[0028] There are generally differences in initial resistance values between diff...
