  • Patent number: 11109796
    Abstract: Exemplary embodiments relate to a skin-adherable electronic device including a semiconductor circuit unit including a circuit element including an electrode and an interconnect, and a semiconductor device including an insulating layer and an active layer; and a flexible patch that can adhere to skin and including a plurality of through-holes, wherein the insulating layer includes a plurality of through-holes corresponding to the plurality of through-holes of the flexible patch, and a method of manufacturing the same. When the active layer is made of a piezoelectric material, the electronic device may be used as a skin sensor that can acquire skin deformation and/or elasticity information.
