The cylindrical electromagnet, which is the basic form of the electromagnet, was fabricated to confirm the possibility of stretchability the electromagnet. Finally, the patch-type electromagnet was manufactured. In the patch-type electromagnet, a wire-PDMS layer was fabricated at the lower part to minimize the rejection reaction when the body was attached, and the Fe / PDMS sponge was stacked at the upper part to improve the electromagnet performance and stretchability. As a result of magnetic field measurement experiment of the fabricated patch-type electromagnet, it is necessary to make the magnetic field 10 times stronger in order to use it as an electromagnet patch. Therefore, it is necessary to change the wire shape from the spiral to the horseshoe shape and to convert the wire type into the insulated wire with good bonding strength with the PDMS / sugar / Fe powder so that more wire can be wound.Maste
