Problems solved by technology

However, when piezoelectric powder is used, there is a limitation that a sensing error occurs because the piezoelectric performance is low and thus the output value is low
In addition, there is a limitation of sensing errors due to irregular voltage output due to irregular mixing of piezoelectric powder
In addition, a piezoelectric body using piezoelectric ceramic powder has a limitation that it is not easy to apply the piezoelectric body using the powder to various devices due to high brittleness

Abstract

The present invention provides a pressure sensor and a composite element having the same, the pressure sensor comprising: a first and a second electrode layer that respectively have first electrodes and second electrodes arranged spaced apart and facing each other; and a piezoelectric layer that is arranged between the first and the second electrode layer, wherein the piezoelectric layer includesa plurality of piezoelectric bodies having a plate shape arranged in a polymer. In addition, the multiple piezoelectric bodies are arranged in one direction and the other direction crossing each otherin the horizontal direction, and in the vertical direction. By using a piezoelectric body having a plate shape, the present invention exhibits excellent piezoelectric properties compared to existingpiezoelectric powders, and as a result can easily sense even a minute pressure thereby improving sensing efficiency.

Description

technical field [0001] The present invention relates to a pressure sensor, and more particularly to a piezoelectric pressure sensor and a complex device having said piezoelectric pressure sensor. Background technique [0002] In general, keyboards have been widely used in devices such as personal computers (PC) and network terminals as tools for interfacing between devices and users. Most keyboards are provided with a mechanical configuration in which springs and switches are installed under keys made in the form of injection molded articles, and key input is obtained by the user hitting the keys with a certain force to obtain the springs Elastic force and make switch can carry out operation. [0003] Meanwhile, besides keyboards provided with such a mechanical configuration, keyboards employing a touch panel type have appeared. Keyboards employing a touch panel type each have technical tools for detecting and recognizing touch or non-touch of a human body (finger) or a pe...
