Discrete ultrasonic electronic skin system

Abstract

A discrete ultrasonic electronic skin system comprises an ultrasonic generator, an ultrasonic receiver, a decoding comparison module and an elastic strain material. The ultrasonic generator, the ultrasonic receiver and the decoding comparison module are integrated in target equipment needing tactile feedback; the elastic strain material covers the surface of target equipment needing tactile feedback, and the elastic strain material can be detached and replaced. Tactile information is calculated by comparing the difference of ultrasonic signals reflected before and after the elastic strain material touches an external object.

Description

Technical Field

[0001] The present invention provides a discrete ultrasonic electronic skin system, belonging to the field of tactile sensing. Background Art

[0002] Conventional tactile sensing devices need to integrate elastic strain materials with measurement units, resulting in high replacement costs for tactile sensors. In the present invention, the elastic strain materials are separated from the measurement units, and only the elastic strain materials need to be replaced, reducing the replacement costs of tactile sensors. Summary of the Invention

[0003] Aiming at the defect that traditional tactile sensing devices need to be replaced as a whole during replacement, the present invention provides a discrete ultrasonic electronic skin system.

[0004] Description of the Drawings: Figure 1 is the structural schematic diagram of the discrete ultrasonic electronic skin system.

[0005] The discrete ultrasonic electronic skin system includes: an ultrasonic generator, an ultrasonic receiver, a decoding and comparison module, and elastic strain materials.

[0006] The ultrasonic generator, the ultrasonic receiver, and the decoding and comparison module are integrated inside the target device that requires tactile feedback; the elastic strain materials cover the surface of the target device that requires tactile feedback, and the elastic strain materials can be disassembled and replaced.

[0007] The working principle is as follows: In the first step, the ultrasonic generator generates ultrasonic waves, the strain materials reflect the ultrasonic waves, the ultrasonic receiver receives the reflected waves and transmits the signals to the decoding and comparison module, and the decoding and comparison module records the original decoded signals; in the second step, when the target device that requires tactile feedback touches an external object, the strain materials deform, the ultrasonic generator generates ultrasonic waves, the strain materials reflect the ultrasonic waves after deformation, the ultrasonic receiver receives the ultrasonic waves reflected after the deformation of the strain materials and transmits the signals to the decoding and comparison module, the decoded signals of the ultrasonic waves reflected after the deformation of the strain materials are compared with the original decoded signals to obtain the deformation information of the strain materials, and the tactile information of touching the external object is calculated through the deformation information of the strain materials.

[0008] After replacing the elastic strain materials, it is necessary to calibrate them.

[0009] The above is the full description of this patent.
