Problems solved by technology

In the patent application CN201380070603, it is disclosed that when the capacitive pressure touch sensor is subjected to a force of 100N, the deformation of the electronic device is about 1.3um. Sensitivity is very low
That is to say, the user experience effect of the above-mentioned products is poor, causing the application of this new sensor to be greatly limited.

Abstract

The invention provides a capacitive pressure touch sensor. The capacitive pressure touch sensor comprises an upper electrode, a lower electrode and a binder bonded to the upper electrode and the lowerelectrode. The binder comprises a transparent resin adhesive and nanometer calcium copper titanate according to a mass ratio of 100: 0.1-20. The invention also provides an electronic component and anadhesive. Through use of a certain amount of CCTO with a certain particle size in the transparent resin adhesive, the adhesive is obtained. The adhesive can significantly improve touch sensitivity ofthe capacitive pressure touch sensor and basically does not influence the light transmittance.

Description

technical field [0001] The invention relates to the field of pressure touch sensors, in particular to a capacitive pressure touch sensor and electronic components. Background technique [0002] Among the existing mobile phone touch panels, a small number of mobile phone products use capacitive pressure touch sensors (detecting the magnitude of pressure through changes in capacitance), such as Apple's patent application CN201380070603 or Iphone 6S. There are also reports of other capacitive pressure touch sensors in the prior art. For example, a variable capacitive pressure sensor and a real handwriting stylus are disclosed in the patent application CN201610147520.4. The variable capacitive pressure sensor includes pressure variable Capacitor, pressure touch switch, with pressure detection function; real handwriting stylus includes real handwriting optical stylus, real handwriting electromagnetic stylus, with pressure sensitivity function, and has the writing effect of real h...
