Embodiment Construction

[0014] The present invention will be further clarified below in conjunction with specific drawings. This specific embodiment is implemented on the premise of the technical solution of the present invention. It should be understood that these modes are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0015] Such as figure 1 As shown, the simulated skin with built-in tactile feedback includes a film 2 and more than one piezoelectric ceramic sheet 1. The film 2 can use a silicon rubber film, and the piezoelectric ceramic sheet 1 is bonded to the silicon rubber film, and each piece of piezoelectric ceramic film is drawn out. The electrode signals on both sides of the ceramic sheet are sent to the processor, and more than one piezoelectric ceramic sheet is pasted on the silicone rubber film according to the designed interval to form the structural unit of the touch feedback skin.

Abstract

The invention discloses simulated epidermis with built-in tactile feedback. The simulated epidermis comprises more than one piezoelectric ceramic piece and a film, the piezoelectric ceramic pieces are adhered on the film to form simulated epidermis structural units, and signals of electrodes on two sides of a piezoelectric ceramic piece of every structural unit are led out to a processor. Concave-convex waves arranged on the surfaces of the films of the structural units to form touch areas, generate different vibrations when touched and act on the piezoelectric ceramic pieces below the film, the piezoelectric ceramic pieces sense the signals and transfer the sensing signals to the processor, and the processor applies feedback to drive the signals on the piezoelectric ceramic pieces according to the received signals. The simulated epidermis with built-in tactile feedback is capable of simulating expression, the skin and organs of a human body or other feedback modes such as voice, has a large development space in the application fields of simulation robots, artificial limb epidermis of the disabled and the like and can enhance realistic feeling of man-machine communication.

Description

technical field [0001] The invention belongs to the field of application technology of piezoelectric ceramics, and in particular relates to a simulation skin with built-in tactile feedback. Background technique [0002] Piezoelectric ceramic materials have a unique piezoelectric effect, which can convert mechanical energy into electrical energy, and can also convert electrical energy into mechanical energy. Under the action of external vibration or impact, piezoelectric ceramics produce microscopic deformation and output charge signals. The piezoelectric ceramic acts as a sensor. Under the action of an electric field, piezoelectric ceramics will produce stretching deformation or vibration, and piezoelectric ceramics will play a driving role at this time. Modern humanoid robots have dull surfaces and lack tactile feedback. Obviously can not meet the needs of use. Contents of the invention [0003] Purpose of the invention: Aiming at the deficiencies in the prior art, th...
