Abstract

The invention discloses a capacitive touch sensor having a patterned microstructure array. The capacitive touch sensor is formed by fingerprint-shaped surface micro-protrusion, an upper capacitive electrode substrate, an upper capacitive electrode, a two-dimensional sine micro-protrusion dielectric layer, a lower capacitive electrode and a lower capacitive electrode substrate which are laminated from the top to the bottom in turn. The fingerprint-shaped surface micro-protrusion is used for receiving external force stimulation. The upper and lower capacitive electrode substrates are used as structural support. The series connection direction of the electrode pole pieces of the upper and lower capacitive electrodes are orthogonally arranged, and the upper and lower capacitive electrodes and the two-dimensional sine micro-protrusion dielectric layer form the capacitor body of the sensor together. After the upper surface of the fingerprint-shaped surface micro-protrusion is affected by external force stimulation, the change of capacitance is sensed by the capacitor body and the size and the direction of the force are acquired through conversion. The problem of high sensitivity real-time detection of the sensor for multidimensional force can be solved, and the sensor can be applied to the field of artificial limbs and surgical manipulators having high requirement of sensitivity.

Description

technical field [0001] The invention relates to a flexible touch sensor, in particular to a capacitive touch sensor with a patterned microstructure array. [0002] technical background [0003] In order to make the working and behavioral capabilities of robots as close as possible to humans, and to be able to work with humans, in addition to more precise motion and operation control, a recognition and perception system close to humans is also required. Usually, the control of the robot is mainly accomplished through the continuous feedback of the spatial position information of mechanical parts or certain image recognition information. The appearance of the tactile sensor makes it increase the contact information between the mechanical parts and the external environment on the original basis, making the mutual feedback between the mechanical parts and the control program more perfect. At the same time, tactile sensors are also building a new human-machine interface between h...
