Systems and methods for wireless neurosensing

Abstract

Systems and methods for neurosensing are provided. A wireless neurosensing system (WiNS), which can be battery-less and/or multichannel, can include a sensor that receives an external electromagnetic (EM) signal (i.e., a carrier signal) through biological tissue communication. The sensor can be configured to be implanted into a subject (e.g., an organoid or a mammalian subject, such as a human subject) and can be referred to herein as the implant. The external EM signal can be received from an interrogator configured to remain outside the subject. The sensor can mix the carrier signal with an electrical signal of interest (SoI) and transmit it back to the external interrogator for posterior demodulation and/or processing. The systems and methods can be employed in many applications to measure the electrical signal in biological or non-biological settings.
