For Wireless Recording and Stimulation Applications

Triangle BioSystems, presents the perfect solution for longterm wireless recording and stimulation applications. This unique inductive power accessory  is designed to keep a wireless headstage's internal battery perpetually charged, thereby enabling indefinite and uninterrupted device operation.

The wireless power system consists of four major pieces: a proprietary non-linear power amplifier, a custom-sized magnetic field emission coil, a magnetic field harvester coil, and a power harvesting circuit installed within the head-mounted device. The power amplifier provides AC power to the emission coil, which induces a harmless magnetic field within its perimeter. The harvester coil, tuned to receive maximal energy from the magnetic field, feeds any gathered energy to the harvester circuit. The harvester circuit then utilizes this energy to power the wire­ less device and to rechargeits internal battery.

This inductive power accessory opens up a previously unavailable experimental paradigm, allowing longterm continuous monitoring or stimulation of the brain while facilitating natural animal behavior.



•Enables indefinite recording time for W/S-Series headstages
