Embodiment Construction

[0022] The specific embodiment of the present invention will be described with reference to the accompanying drawings.

[0023] The shape and size of the sensor proposed by the present invention have no special regulations, but it is better to make the semiconductor sheet cover as many pores as possible. If a semiconductor sheet with a regular shape is used, it is beneficial to determine the functional relationship between the output voltage and the change of the pore diameter for future practical application. For example, when a rectangular semiconductor silicon wafer is used in the embodiment of the present invention, a Gaussian function relationship can be detected. The semiconductor material used in the present invention includes commonly used materials such as silicon, germanium, gallium arsenide, etc., and the doped impurities include commonly used boron, phosphorus, etc.

[0024] The present invention is described by taking a rectangular semiconductor silicon wafer as ...

Abstract

A diameter sensor of human hair trichopore is a doped semiconductor chip which is serially connected in a DC circuit and can be stably pasted on human skin. If a constant current source is used in said DC circuit, the two power inputs of said semiconductor chip are signal outputs. If a constant voltage source is used, the current flowing through said semiconductor chip is just the output signal. Its signal processing circuit is composed of small signal amplifier, logrithmic operation circuit and extraction operating circuit.

Description

technical field [0001] The human body pore aperture displacement sensor and its signal processing circuit belong to the technical field of semiconductor intelligent sensor design of bioelectronics. Background technique [0002] Pore ​​diameter is an important information window of human physiological changes. It can not only be used as an appearance parameter, but also reflect the suitability of cold and heat inside the human body, the degree of metabolism, and even the development of some diseases. After searching, there is no literature on the sensor and its signal processing circuit that can respond to the change of the pore diameter of the human body in the domestic and foreign literature. Contents of the invention [0003] The purpose of the present invention is to propose a sensor that can effectively respond to changes in the pore diameter of the human body. The sensor uses a semiconductor chip to sense the array pores, and uses the thermal effect to convert the rad...
