Subdermal “subcutaneous” implants are three-dimensional objects placed under the skin usually for aesthetic reasons. Silicon-coated magnets can be implanted to create a sense of “magnetic vision”. Coated RFID chips can also be implanted for use with security devices or for the purpose of data storage.
3-D Subdermal Implants can also be stretched just like piercings. After an implant has healed, it can be removed and replaced with a slightly larger implant. This can be done repeatedly until the desired size is reached.
Materials safe for subdermal implants are implant grade silicone, teflon, titanium & stainless steel.
