Embodiment Construction

[0027] In order to better understand the purpose, structure and function of the present invention, a pressure sensor based on friction power generation of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0028] like figure 1 and figure 2 As shown, it describes the first embodiment of the pressure sensor based on triboelectric generation of the present invention. Wherein, the pressure sensor of this embodiment includes a pressure bearing part 1 and a base 2 which are arranged facing each other, the pressure bearing part 1 and the base 2 are connected by a plurality of guide rods 5, and the guide rods 5 are sleeved with elastic parts 4, Specifically, the elastic part 4 is a spring sleeved on the guide rod 5 between the pressure-bearing part 1 and the base 2, so that when an external force is applied to the pressure-bearing part 1, the pressure-bearing part 1 can move relative to the base 2 , thereby changing the ...

Abstract

The invention discloses a pressure sensor based on friction power generation. The pressure sensor comprises a pressure bearing part (1) and a base (2), and a friction power generation part (3) is arranged between the pressure bearing part (1) and the base (2). The friction power generation part (3) is connected with an external circuit, and when pressure acts on the pressure bearing part (1) and enables the distance between the pressure bearing part (1) and the base (2) to be changed, the friction power generation part (3) can generate the electric quantity used for displaying pressure changes in the external circuit. The pressure sensor based on friction power generation is high in precision, wide in measuring range, simple in structure and good in anti-interference performance.

Description

technical field [0001] The invention relates to the technical field of sensors, in particular to a pressure sensor based on friction power generation, which can be conveniently applied in various industrial automatic control environments. Background technique [0002] Pressure sensor is the most commonly used sensor in industrial practice. It is widely used in various industrial automatic control environments, involving water conservancy and hydropower, railway transportation, intelligent buildings, production automatic control, aerospace, military industry, petrochemical, oil wells, electric power, ships, machine tools , pipeline and many other industries. [0003] Currently commonly used pressure sensors are mainly capacitive pressure sensors and resistance strain pressure sensors. Common capacitive pressure sensors are mainly electrostatic capacity type, for example, the fixed pole of glass and the movable pole of silicon are arranged oppositely to form a capacitance, an...
