Abstract

The invention discloses a flexible tactile sensor unit, a tandem strip-shaped flexible tactile sensor and a tactile distribution monitoring method thereof. The sensor unit comprises a signal processing unit and a plurality of sensing elements, and the sensing elements are of a tandem strip-shaped structure and are connected to the signal processing unit through a common signal baseline. The tandemstrip-shaped flexible tactile sensor comprises a total signal processor and the flexible tactile sensor unit. The flexible tactile sensor unit is of a tandem strip-shaped structure. The tactile distribution monitoring method comprises the following steps: s1, constructing a surface position coordinate system of a monitored object according to the surface geometry of the monitored object; and s2,tightly and continuously winding and binding the tandem strip-shaped flexible tactile sensor to the surface of a to-be-tested object, and establishing a mapping between the surface position coordinatesystem of the monitored object and the sensing element distribution of the tandem strip-shaped flexible tactile sensor to achieve curved surface tactile monitoring.

Description

technical field [0001] The invention relates to the field of series-connected strip-shaped flexible tactile sensors, in particular to a flexible tactile sensor unit, a series-connected strip-shaped flexible tactile sensor and a method for monitoring its tactile distribution. Background technique [0002] In order to enable intelligent robots to obtain intuitive human-computer interaction bionic functions, or to obtain the pressure distribution on the surface of a special device, or even to monitor certain physiological signals from the human surface in real time, flexible tactile sensors (or electronic skin) have become A realistic technical need. The highly sensitive wearable electronic skin attached to the surface of the human body has been able to obtain physiological health information such as blood pressure and heart rate by monitoring "tactile signals" such as tiny pressure / strain. Since today's electronic skin technology is still mainly in the laboratory research sta...
