A method of manufacturing a flexible piezoelectric device including laminating a first metal layer on a silicon oxide layer on a silicon substrate. The method further includes laminating a device on the first metal layer and annealing the first metal layer to oxidize the first metal into a first metal oxide. The method further includes etching the first metal oxide to separate the device from the silicon oxide layer and transferring the separated device to a flexible substrate using a transfer layer. The metal oxide layer laminated on the silicon substrate is etched to separate the device from the substrate. As a result, physical damage of the silicon substrate is prevented and a cost of using expensive single-crystal silicon substrate is reduced.
