Problems solved by technology

The invention comprehensively considers the texture and biological characteristics of the skin, and solves the problems of artificial skin that cannot be spliced ​​and flexibility. At the same time, it adopts an active method to sense pressure, frequency and even temperature, and will not cause short circuit due to unevenness and bending of the body surface. The active way is to generate self-inductance current through the inductance coil

Abstract

The invention discloses a sensor for bionic skin, a coil array, a positioning method and a touch collector. An inductance coil array structure for the bionic skin comprises an ADC analog-to-digital conversion circuit and multiple groups of magnetoelectric sensors; each group of magnetoelectric sensors are correspondingly accessed to various input ends of the ADC analog-to-digital conversion circuits in a parallel way, and the distance between each group of magnetoelectric sensors is equal; each group of magnetoelectric sensors comprise multiple magnetoelectric sensors, and multiple magnetoelectric sensors in the group are connected into the same corresponding loop in parallel; the magnetoelectric sensor adopts the sensor for the bionic skin disclosed by the invention; furthermore, the expansion splicing can be performed on the basis of a contact point occurrence location positioning method for bionic skin, various magnetoelectric sensor parallel loops in each group can perform parallelconnection extension to the Y axle; and the splicing of the whole positioning circuit on the plane is realized by extending the parallel loop on the x axle by adding the input end connecting pin of the ADC analog-to-digital conversion circuit.

Description

technical field [0001] The invention relates to the technical field of bionic skin, in particular to a bionic skin sensor, a coil array, a positioning method and a tactile collector. Background technique [0002] The Subramanian Sundaram stretchable haptic glove at the MIT Computer Science and Artificial Intelligence Laboratory has 548 sensors and 64 conductive wire electrodes. The sensor array consists of a tension-sensitive film and a network of conductive threads. Every point of coincidence between the electrode and the membrane is sensitive to perpendicular force and registers the resistance through the membrane. [0003] Although the existing artificial skin uses sensors to locate the contact position, the cost is still high, and the accuracy of pressure, temperature and frequency changes is low. Most film products cannot be accurately positioned, and the scalability and splicing performance are poor. Printing or other rubber products are not soft enough to touch and ...
