Method for realizing multiple functions on mobile terminal by single piezoresistive sensor

Abstract

The invention discloses a method for realizing multiple functions on a mobile terminal by a single piezoresistive sensor. According to the method, after deformation from GAP is sensed through the piezoresistive strain sensor, minute changes thereof are converted into voltage values, and after collection is carried out through ADC, a specific pressure value is finally reported to the mobile terminal through algorithm processing; and then the mobile terminal distinguishes and realizes the multiple various functions according to pressed areas of a touch screen. According to the method, the multiple functions are realized through combining the single sensor and the mobile terminal, a traditional design that the multiple functions can be realized only by full-screen sensors or multiple sensorsis replaced, a structure is simple, and realization is easy; and costs of the piezoresistive strain sensor are also reduced while multifunctional experience of a user is improved, and production and mass production yield is improved.

Description

technical field [0001] The invention belongs to the technical field of touch screens, and in particular relates to a method for realizing multiple functions in a mobile terminal through a single piezoresistive sensor. Background technique [0002] Traditional piezoresistive strain sensors are generally only used as a single home button function on mobile terminals. If you want to achieve multi-functions, such as the accelerator in the lower right corner of the game, and the brake in the lower left corner, you must use a full-screen sensor or multiple sensors. of. [0003] The device and method for realizing multi-function of a single piezoresistive sensor in a mobile terminal is greatly improved compared with the traditional one that only realizes the function of a single home button, or requires a whole screen sensor or multiple sensors to realize multi-function. The single function of the traditional single piezoresistive strain sensor requires multiple piezoresistive str...

[0005] However, the pressure sensor has a plurality of pressure-sensitive parts to form a microstructure array, through which the detection of the pressure value is realized. In fact, multiple sensors form the structure of the entire screen sensor, which still has the disadvantages of complex structure and high cost.
