Perspective in Nanoneural Electronic Implants With Wireless Power-Feed and Sensory Control

New medical device technology is essential for diagnosing, monitoring, and curing wide spectrum of diseases, anomalies, and inflictions. For neural applications, currently available devices are generally limited to either a curing or a probing function. In this paper, we review the technology requirements for a new neural probe and cure device technology currently under development. The concept of the probe-pin device that integrates the probes for neurochemistry, neuroelectricity, temperature, and pressure into a single embodiment with a wireless power transmission was designed for the purpose of deep brain feedback stimulation (DBFS) with in situ neural monitoring. The probe considered for monitoring neurochemistry is a microspectrometer. The feature and size of the microspectrometer are defined for the DBFS device. Two types of wireless power transmission technology were studied for the DBFS device operation. The test results of pig skin showed that both power transmission technologies demonstrated the feasibility of power feed through human tissue.
