Abstract

The invention discloses a piezoelectric skin detector, and relates to the technical field of biological sensor and piezoelectric sensing. Non-invasive living body measuring of a small measuring devicecan be realized. The piezoelectric skin detector comprises a probe, a conduction assembly, a sensing assembly and a signal collecting module. One end of the probe makes contact with a to-be-measuredsurface, and the other end of the probe makes contact with the conduction assembly. The conduction assembly is connected with the sensing assembly in a clinical contact state. The sensing assembly isconnected with the signal collecting module. The probe transmits contact body surface conditions to the sensing assembly through the conduction assembly. The sensing assembly generates output signalsthrough the contact input signals. The signal collecting module collects the output signals of the sensing assembly. Through the positive piezoelectric effect, non-invasive detection of skin state information is realized, some physical and chemical information in skin is converted into charge or voltage information, auxiliary reference is provided for representing the physiological state of skin,and the piezoelectric skin detector has the advantages of being simple in structure, rapid in response, rich in detection information, high in comfort, free of invasion and the like.

Description

technical field

[0001] The invention relates to the technical fields of biological sensors and piezoelectric sensing, in particular to a piezoelectric skin detector. Background technique

[0002] The skin surface is a mirror of the physiological health of the human body. Through the detection and feedback analysis of the performance parameters of the skin tissue, it can provide a reference for qualitative and quantitative evaluation of the current state of the skin. As the largest tissue and organ of the human body, the skin is the medium for the exchange between the human body and the external environment. It has complex physiological functions and is affected by many factors such as body fluids, metabolism, and physical and chemical environments. The realization of the physiological functions of the skin depends on its biomechanical properties. , such as viscoelasticity, tension, compression resistance, etc. Detecting the biomechanics, shape, size, position and other char...
