Triangle BioSystems, Inc. has developed a high channel count

wireless neural headstage system that allows researchers to

continuously and simultaneously monitor up to 29 neural

electrodes. No longer do experiments have to be constrained by

wiring a test subject to the recording system. The complete

system is comprised of a wireless headstage transmitter with

integrated battery, RF signal receiver/baseband demodulator,

power supply and all required cables. With an effective range of 3

meters, this system provides a wireless connection between the

implanted electrodes and the data recording system.

In the development of this system, TBSI utilized custom ASIC

technology and proprietary radio design techniques to provide high

channel count functionality in a wireless headstage that is both

small and light weight (<7.2 grams). This design also incorporates

neural preamplifier circuitry to create an extremely compact and

powerful transmitter.
