Abstract

The invention discloses a three-dimensional force flexible tactile sensor and a preparation method and a decoupling method thereof, wherein the three-dimensional force flexible tactile sensor comprises a first flexible layer, a porous elastic layer and a second flexible layer which are arranged in sequence; and the first flexible layer is provided with a plurality of first electrodes, the second flexible layer is provided with a second electrode, and the first electrodes and the second electrode are both clung to the porous elastic layer. The sensor not only can detect forward mechanical load,but also can measure force tangent to the surface of the sensor, so that detection of three-dimensional force is realized.

Description

technical field [0001] The invention relates to the technical field of flexible sensors, in particular to a three-dimensional force flexible tactile sensor, a preparation method and a decoupling method thereof. Background technique [0002] With the development of artificial intelligence, there is an increasing demand for flexible electronic devices, including flexible sensors, wearable energy generators, wearable organic diodes, and soft robots, etc. In these state-of-the-art electronic devices, many flexible sensors are required to not only detect the normal force / pressure on the sensor surface, but also simultaneously sense tangential loads. [0003] There are currently many sensing principles to detect three-dimensional loads, including piezoelectric, resistive, capacitive, and optical techniques. As one of the most commonly used methods, the resistive three-dimensional force sensor is composed of conductive sensing elements such as conductive rubber or metal. Variety....
