SCH: INT: Collaborative Research: Physiological Studies of Brain Signals using a Wireless Neuro-Sensing-Diagnostic System

该项目的目标是开发一种完全无源的颅内传感系统。这种新颖的电子脑机接口采用了基于微波背向散射的可植入微型神经传感器、微型纺织天线和柔性聚合物衬底上的射频电路。它具有只需少量加热的独特特性，从而将对大脑的伤害和创伤降至最低，消除了通过头盖骨的电线的需要，并保持了自然的生活方式和舒适性。获取的神经信号由自供电可穿戴体域网络收集，用于连续实时监测和随后的生理解释。该项目包括对获得性大脑信号的生理学研究。虽然最初的设想是作为一种长期监测大脑信号的工具，但这种传感技术在健康方面具有非常广泛的潜在应用，包括控制假肢和早期检测癫痫发作。克服传统神经传感器技术在安全性和长期可靠性方面的挑战，可以改变患有严重慢性神经疾病的人的医疗保健。生理学研究的结果通过数据仓库传播，以了解大脑疾病。通过几项活动将研究与教育结合起来，包括为这一新领域的学生提供实践经验、夏令营和各种外展活动，以吸引工程领域的妇女和少数群体。

The goal of this project is to develop a fully-passive intra cranial sensing system. This novel electronic brain-machine interface utilizes an implantable miniaturized neurosensor based on microwave back-scattering, a miniature textile antenna, and RF circuits on flexible polymer substrate. It has the unique properties of only minor heating, thus, minimizing injury and trauma to the brain, eliminating the need for wires through the cranium, and preserving natural lifestyle and comfort. The acquired neurosignals are collected by a self-powered wearable body area network for continuous real-time monitoring and subsequent physiological interpretation. The project includes physiological studies of the acquired brain signals. While conceived initially as a tool for long-term monitoring of brain signals, this sensing technology has a very wide range of potential applications in health, including control of prosthetics and early detection of seizures. Overcoming the challenges in safety and long-term reliability presented by conventional neurosensor technology could transform healthcare for people suffering from severe chronic neurological disorders. Results of the physiological studies are disseminated through a data repository for understanding brain disorders. Research is integrated with education through several activities, including hands-on experience for students in this new area, summer camps, and a variety of outreach activities to attract women and minorities in engineering.
