A neurological disorder is a chronic discomfort that affects many people throughout the world. The major form of treatment is long-term drug therapy, and surgery is an alternative for patients who do not respond to drug treatment when the cause is limited to a region. Continuous monitoring of neural activity is commonly used for the diagnosis of abnormal zones. Thanks to the advances in electronics, sensor systems, and fabrication methodologies, this book proposes an entirely implantable wireless neural monitoring system which eliminates the wires and possible complications due to them. This chapter presents the motivation of a wireless implantable neural recording system. It describes the challenges while removing the wires going from intracranial sensors to an external device outside of the body.
