Problems solved by technology

At present, the main solution is to use batteries, but the battery technology itself has many shortcomings, such as poor power supply durability, serious environmental pollution, and large consumption of material resources.
These shortcomings will limit the application of batteries in related fields
In addition, the acceleration is measured through an external power supply. Once there is a problem with the external power supply or the line connected to the external power supply, real-time and accurate measurement of the acceleration cannot be achieved.

Abstract

The invention relates to the technical field of generators, and discloses an accelerometer. The accelerometer comprises a friction conductive part (1) and a moving part (2), wherein the friction conductive part (1) comprises a first electrode (11) and a second electrode (12) arranged at an interval; and the moving part (2) is arranged corresponding to the friction conductive part (1), relative movement can be generated with the friction conductive part (1) during the acceleration period of the accelerometer, friction charges are generated on the first electrode (11) and / or the second electrode (12), and thus, a friction potential difference for characterizing the acceleration is formed between the first electrode (11) and the second electrode (12). The accelerometer of the invention can generate the friction potential difference for characterizing the acceleration in the case of acceleration.

Description

technical field [0001] The invention relates to the technical field of generators, in particular to an accelerometer. Background technique [0002] With the rapid development of the automobile industry, aerospace, navigation and guidance and other fields, acceleration is an important parameter, and the determination of acceleration restricts the application of related technologies. Among them, an external power supply is generally required when measuring acceleration, so it is particularly important to solve the problem of power consumption in a small range. At present, the main solution is to use batteries, but the battery technology itself has many shortcomings, such as poor power supply durability, serious environmental pollution and large consumption of material resources. These disadvantages will limit the application of batteries in related fields. In addition, the acceleration is measured through an external power supply. Once there is a problem with the external po...
