Brain computer interface (BCI) technology has classically focused on two signal acquisition modalities for
control: multi, single-unit activity (MSU) and electroencephalography (EEG). While MSU activity
provides a high fidelity, multi-dimensional signal for BCI control, obtaining long-term stability of single unit recordings has proven difficult at best due to glial encapsulation issues.

Brain-machine interfaces (BMI) and neuroprosthetic technology have the potential to dramatically improve quality of life after paralysis resulting from spinal cord injury, stroke or traumatic brain injury.

Dr. Weinstein will discuss the Resonant Body Transistor (RBT), which can be integrated into a standard CMOS process for low power clock generation and high-Q tank circuits. We recently demonstrated the first hybrid RF MEMS-CMOS resonators in Si at the transistor level of IBM’s 32nm SOI CMOS process, without the need for any post-processing or packaging. The unreleased, Si bulk acoustic resonators are driven capacitively using the thin gate dielectric, and actively sensed using a body-contacted nFET incorporated into the resonant cavity. FET sensing with the high fT, high performance transistors in CMOS amplifies the mechanical signal before the presence of parasitics. The resulting RF-MEMS resonators provide low power, low cost, small footprint building blocks for on-chip signal generation and processing.
