Periodic Reporting for period 1 - REFLEX (High Resolution, Reduced Energy Flexible Electronics for Enhanced Brain-Spine Interfaces (REFLEX))
Okres sprawozdawczy: 2021-06-01 do 2023-05-31
Emerging bioelectronic medical devices (BMDs), are improving treatments for injuries and disorders in the nervous system. But despite recent successes, the lack of minimally invasive BMDs remains a barrier to real-time, closed-loop treatments.
REFLEX leverages ultra low-power backscatter wireless communication and soft, conformable electrode arrays to create minimally invasive, fully-wireless BMDs. In doing so, REFLEX seeks to advance the state-of-the-art in low power wireless sensing as well as fully-integrated electronic devices for fundamental research and clinical therapies.
- First in vivo validation of Bluetooth Low Energy backscatter communication, demonstrating the ability to detect and transmit microvolt-level auditory evoked potentials to off-the-shelf receivers at orders-of-magnitude lower power levels. To be published at Transducers 2023.
- Development of a fully-wireless method for corrosion detection enabling high-resolution measurements of water vapor transmission rate (WVTR) to test and validate implant encapsulations. Publication to be submitted.
- Design and validation of a generalized, all-digital vector modulation scheme for low-power backscatter communication systems. Publication submitted May 2023.
- Analysis and measurement of gain pattern distortion due to dielectric resonator effects arising in small animal host bodies. Publication submitted April 2023.
