Stretchable rigid-flex interconnector and manufacturing method therefor

A manufacturing method for a stretchable rigid-flex interconnector, comprising:

• providing a stretchable substrate, separately printing silver paste and a liquid metal polymer composite on a first side of the stretchable substrate to form a non-stretchable circuit layer and a stretchable circuit layer, so as to obtain a first rigid-flex composite structure, wherein the non-stretchable circuit layer and the stretchable circuit layer have an overlapping region at an interface;
• providing a sealant, and encapsulating the first rigid-flex composite structure using the sealant to form a sealing layer, so that the stretchable circuit layer is covered by the sealing layer, to obtain a second rigid-flex composite structure;
• and
• providing a support layer, and attaching the support layer to a second side of the second rigid-flex composite structure, to obtain a target rigid-flex interconnector.
