Signal sensor, sensing method and portable electronic equipment

Abstract

The invention discloses a signal sensor. The signal sensor comprises a user input terminal, a first piezoelectric and a signal output unit; the user input terminal is used for enabling a user to slide on the user input terminal; the first piezoelectric is used for responding a thrust of the user sliding on the user input terminal to generate stress deformation, and induces the first piezoelectric surface with charges; a prepolarized direction of the first piezoelectric is parallel with the direction of the thrust in the same plane; and the signal output unit is used for outputting the charges on the first piezoelectric surface as the sensing signals. The invention further discloses a signal sensing method and portable electronic equipment. After adopting the invention, electric sensing signals can be generated directly without a signal processing device; various specific applications of a signal sensor control device can be utilized directly without interferes of other equipment processors, thus the invention is great suitable to various kinds of portable electronic equipment, saves cost, can avoid interfere generated by static electricity and has wider application range.

Description

technical field [0001] The invention relates to the field of sensing technology, and more specifically, to a signal sensor, a sensing method and a portable electronic device. Background technique [0002] In the consumer electronics market, there is a clear and strong need for products that can be controlled by simple user interactions. To achieve this goal, more and more input devices are being developed that provide control signals for different functions. One area of ​​input devices that is not perfect is the swipe sensor. This kind of sensor senses the operation of scratching or sliding on the surface of the device (such as mobile phone, MP3 player, etc.) to perform various specific applications (such as controlling the volume of the speaker, etc.). For this application, touch screens can be implemented using the working principle of capacitive touch sensors. [0003] Existing swipe sensor technologies for non-screen applications mainly use vibration and sound detectio...

Problems solved by technology

[0004] However, the current existing sliding sensors only provide different signals carrying different contents, and signal processing devices are required to analyze and process operations such as controlling the volume, but cannot directly provide external sensing signals that can be used as electrical control signals

[0005] Not only that, one of the key challenges of the swipe sensor, whether it is in the non-screen field or the screen field, is that it may often provide false outputs due to static electricity, resulting in false control signals
