Jakob Voigts is at the McGovern Institute for brain research at MIT. He is a co-founder of Open Ephys dedicated to open source methods development across the electrophysiology community.

The flexDrive is a chronic drive implant for extracellular electrophysiology that can be used to individually position up to 16 microwire electrodes or electrode bundles in mice, with up to 64 channels. The implant weighs approximately 2 grams, so it can be used in freely moving mice. The small size of the design also makes it possible to target off-center areas, or even to fit a drive implant under a microscope for simultaneous imaging and electrophysiology. The flexDrive is easy to build, accommodates arbitrary spatial arrangements of electrodes, and is compatible with a variety of recording systems (though it is best used with lightweight digital Open Ephys compatible headstages).

Channel count: 16 drives, up to 4 channels per drive. Weight: ~2g for 16 tetrode drives.

Package includes: 1x drive body (1 mil ultra high precision 3D print, ready to use, no drilling required), 2x stainless steel springs, 3 types of polyimde tubes (26ga 140mm; 33ga 1210mm; 37ga 450mm). Reusable screws not included, order separately.
