Hybrid CMOS-Graphene Sensor Array for Subsecond Dopamine Detection.

We introduce a hybrid CMOS-graphene sensor array for subsecond measurement of dopamine via fast-scan cyclic voltammetry (FSCV). The prototype chip has four independent CMOS readout channels, fabricated in a 65-nm process. Using planar multilayer graphene as biologically compatible sensing material enables integration of miniaturized sensing electrodes directly above the readout channels.

Technical design of a new bone conduction implant (BCI) system.

Objective: The objective of this study is to describe the technical design and verify the technical performance of a new bone conduction implant (BCI) system.

Design: The BCI consists of an external audio processor and an implanted unit called the bridging bone conductor. These two units use an inductive link to communicate with each other through the intact skin in order to drive an implanted transducer.
