In this embodiment, the material of the flexible transfer body 11 is, for example, PDMS, PMMA, hydrogel, resin, but is not limited thereto.

[0042] The transfer device of the present application can make the surface 111 of the flexible transfer body 11 protrude by irradiating the particles 12 in the flexible transfer body 11 with light or microwaves, reduce the adhesion area of the flexible transfer body 11 and the device 21 to be transferred, and further reduce the adhesion force, transfer the device 21 to the object by protrusion, fast transfer speed, simple operation and low cost.

Preferably, the pattern is a plurality of concentric circles or a plurality of concentric ellipses, with the circles or ellipses spaced apart from each other.

Figure 9 This is a schematic diagram of the structure of the transfer device in the third embodiment of the present invention during the transfer process, as shown below. Figure 8 and Figure 9 As shown, the transfer device in this embodiment is largely the same as the transfer device in the first embodiment, except that the distribution pattern of the particles 12 is different.

[0052] Specifically, such as Figure 8 and Figure 9 As shown, multiple particles 12 are disposed close to the surface 111 of the flexible transfer body 11. The surface 111 of the flexible transfer body 11 has multiple bumps 112 corresponding to each particle 12.

Specifically, when the particles 12 inside the first airbag 101 are irradiated with a laser or microwave, the particles 12 inside the first airbag 101 are heated by the laser or microwave and the air inside the airbag is rapidly heated. The first airbag 101 expands due to heat, causing the entire flexible transfer body 11 to bend and deform around the cylinder. Then, the particles 12 inside the second airbag 102 are irradiated with a laser or microwave. The particles 12 inside the second airbag 102 are heated by the laser or microwave. At this time, the local surface 111 of the second transfer layer 114 expands and protrudes, transferring the device 21 onto the cylinder.
