Problems solved by technology

And it is difficult for this kind of motor to reflect the strength of vibration, so the vibration feedback experience is not ideal; compared with conventional electromagnetic brakes such as eccentric rotary motor actuators, piezoelectric actuators with tactile feedback have the best performance. Acceleration and force, the largest insertion height and the shortest response time; at the same time, the electroactive polymer drive technology that has emerged in the past 20 years also has new applications in the field of tactile feedback
DEA (Dielectric Elastomer Actuator) is a kind of flexible polymer material with very high response speed, but DEA materials have always had two bottlenecks: the driving field strength is very high, 1-10MV / m, so the voltage is usually very high (several thousand volts); stability problems, mainly thermal and electrical breakdown problems; Electro-Mechanical Polymer (EMP) is a kind of fluorinated polymer PVDF modified piezoelectric polymer material ( Novasentis)

Abstract

The invention discloses a tactile feedback structure based on PVC gel driving and a manufacturing method and application of the tactile feedback structure. wherein the cathode planar electrode plate,the PVC gel film and the anode mesh electrode plate are sequentially stacked from top to bottom, and the PVC gel film can creep and deform into meshes of the anode mesh electrode plate to generate output displacement for tactile feedback after direct-current voltage is applied to the PVC gel film. The method is simple to operate, the PVCgel responds quickly under voltage, deformation is obvious, and tactile feedback can be output.

technical field [0001] The invention belongs to the technical field of intelligent materials and intelligent structures, and in particular relates to a tactile feedback structure driven by PVC gel and its production method and application. Background technique [0002] Haptic or Tactile Feedbacks can reproduce the sense of touch for users through a series of actions such as force and vibration. This mechanical stimulation can be applied to the auxiliary creation and control of virtual scenes or virtual objects in computer simulation, and to enhance the remote control of machinery and equipment. Vibrators used for haptic feedback technology mainly include the following categories: eccentric rotor vibrator, which simulates a tactile feedback action of a click, which takes 100 to 200 milliseconds. Sluggishness. And it is difficult for this kind of motor to reflect the strength of vibration, so the vibration feedback experience is not ideal; compared with conventional electrom...
