Conformal Electronics Wrapped Around Daily-life Objects Using Original Method: Water Transfer Printing.

International audienceThe water transfer printing method is used to transfer patterned films on random three-dimensional objects. This industrially viable technology has been demonstrated to intimately wrap metallic and polymeric films around different materials. This method avoids the use of rigid substrate during the transfer step. Patterns can be transferred to objects without folds even when holed, addressing a challenging issue in the field of conformal electronics. This technique enables to reach high films bending properties. This promising method, enables to integrate large-area films onto daily-life objects. Bent capacitive touchpad is fabricated showing the potential applications of this technology
