Micropillar with Pt Bridges

A micropillar is provided with lateral contacts in order to generate an in-plane electrical field inside the cavity. The contacts are formed by focused ion beam induced deposition of platinum between a gold layer and the micropillar. The image was colorized (Pt: blue, Au: yellow, micropillar: red).

Wireless Utah Neural Electrode array

The image shows a 10*10, 1.5mm long, 400 micron pitch Utah Neural Wireless Electrode array for communicating with individual neurons from the brain. The substrate consists of machined crisscross channels which are 500 μm deep, filled with glass frits (insulator between each electrode), with backside metallization (not visible in the picture) using microfabricaion techniques for integration with the electronics. The frontside of the array is machined into 100 electrodes on a wafer level followed by acid etching of the columns to form pointed needles with fine surface texture. The tips of all the electrodes are coated with Iridium oxide in order to communicate with neurons during the stimulation and recording from the brain.
