specific Embodiment
[0030] At present, the somatosensory tactile devices on the market mainly act on the tactile stimulation of the human body from the outside. The external stimuli here are mainly divided into two types, one is electrical stimulation, and the other is mechanical stimulation (tactile somatosensory stimulation). The former refers to the use of current pulses to stimulate the skin to stimulate nerve sensory fibers to generate somatosensory stimulation. This method generally requires high equipment performance, expensive, complicated devices, low operational safety, and uncontrollable tactile sensation. types are limited. Tactile stimulation is to stimulate the skin (finger) through electric or magnetic vibration, etc. This method is relatively safe, does not require a complete set of professional equipment, and has a higher degree of acceptance and promotion.

[0034] Please refer to figure 1 , is a schematic exploded view of a cross-sectional structure of a somatosensory haptic device provided in the first embodiment of the present invention, wherein the somatosensory haptic device includes a flexible circuit board 10, an IPMC elastic layer 20 and a strain elastic layer 30, and the flexible circuit board 10 is disposed between the IPMC elastic layer 20 and the strain elastic layer 30 , and the IPMC elastic layer 20 includes a plurality of IPMC structures 210 .
[0035] Here, the flexible circuit board 10 is a printed circuit board made of polyimide or polyester film, which has the advantages of high wiring density, light weight, thin thickness and good bendability, so The flexible circuit board 10 is sandwiched between the IPMC elastic layer 20 and the strain elastic layer 30; the arrangement of the plurality of IPMC structures 210 in the IPMC elastic layer 20 on the IPMC elastic layer 20 It can be set according to the actual situa...

[0061] refer to Figure 6 , which is a method flowchart of a somatosensory haptic control method provided in the second embodiment of the present invention, wherein the somatosensory haptic control method includes:
[0062] Step S200, the controller sends an actuation instruction to the IPMC structure in the IPMC elastic layer;
[0063] Step S300, the IPMC structure is deformed according to the actuation command, and drives the IPMC elastic layer and the strain elastic layer to deform;
[0064] Step S400, the strain gauges in the strain elastic layer acquire pressure data when the strain elastic layer is deformed;
[0065] Step S500, the controller adjusts the actuation command according to the pressure data and expected pressure data.
[0066] Specifically, in step S200, the controller and the IPMC structure in the IPMC elastic layer issue an actuation instruction, the actuation instruction refers to an instruction that can cause the IPMC structure to generate motion, and t...
