Wearing type flexible pressure sensor and preparing method thereof

Abstract

The invention belongs to the technical field of flexible electron sensors, and particularly relates to a wearing type flexible pressure sensor and a preparing method thereof. The wearing type flexible pressure sensor comprises five parts of an upper support substrate, a super soft Ecoflex pressure detection head, PVDF piezoelectric thin film, an array form micro boss support structure and a lower support substrate. The super flexible Ecoflex pressure detection head can sense pressure to deform, and further compress the PVDF piezoelectric thin film to output an electric signal. The invention further discloses the preparing method of the wearing type flexible pressure sensor. The super soft Ecoflex pressure detection head can very sensitively sense weak pulse visual skipping of a human body, and solve the problems that wearable intelligent equipment cannot measure a pressure signal and is not flexible. The wearing type flexible pressure sensor further has the advantages of being small and exquisite in size, comfortable to wear, long in service life, low in preparation cost and the like, and being suitable for being used in large-scale production.

Description

technical field [0001] The invention belongs to the technical field of flexible electronics and sensors, and more specifically relates to a wearable flexible pressure sensor and a preparation method thereof. Background technique [0002] With the development of electronic information technology, wearable smart devices have gradually entered people's lives, which can monitor human body movement, health and other information in real time, which greatly facilitates and enriches our lives. However, the current wearable smart devices have almost no pressure measurement modules, and cannot directly measure some pressure signals of the human body, such as the beating of the human pulse (reflecting the human body's heart rate, blood pressure and other health information). Most of the current wearable smart devices, such as 37-degree smart bracelets, use optical measurement to estimate the blood pressure information of the human body, and are also greatly affected by factors such as ...
