Implantable medical devices, including pacemakers, cochlear implants, neural recording devices, and deep brain simulators, touch every part of the human function. These devices need to communicate with external acquisition equipment that supervise the status of the device and transmit patient data. An antenna is an essential component of this wireless communication system. The size of the antenna is determined by the frequency of the transmitted signal. Specifications for an appropriate half wave antenna in the MedRadio band (402-405MHz) are a length of 36 cm in air and 6 cm or more if it is implanted in the body. These antennae are significantly larger than the implanted device itself (in mm scale). Traditional antenna design restricts the antenna on the medical devices. Our recent novel work has developed a subdermal antenna remotely coupled with a small feed on the medical devices. This approach radically increases the options for antenna size, shape, and configuration (similar to wireless charging technology). However, current materials are mechanically or biologically unsuitable for subdermal applications. This study is focused on designing a flexible, conductive, and biostable nanocomposite for subdermal antenna.
