Title:
PRESSURE SENSOR AND ROBOT
Document Type and Number:
WIPO Patent Application WO/2023/210376
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a pressure sensor that makes it possible to easily measure pressure such as blood pressure and a robot including the pressure sensor. In order to solve the problem, this pressure sensor comprises an imaging element, a light reflecting layer opposed to an imaging surface and disposed with a space from the imaging element, the light reflecting layer having reflective characteristics that change depending on pressure, and a light source for emitting light that enters the space between the imaging element and the light reflecting layer, and pressure is detected from a change in an image captured by the imaging element when pressure is applied from a side of the light reflecting layer facing away from the imaging element, with the light from the light source entering the space between the imaging element and the light reflecting layer.
