The control electronics include an Arduino, a motor controller, and a heat sink attached to one of the silver electrodes. Communication is done through USB, and of course there’s a mobile app ...

both stripped with silver electrodes approximately 30 μm high. “First, we place the solar cell in an aluminum chloride solution. The aluminum electrode is removed from the silicon wafer.

Dopamine sensor demonstration To illustrate the quality of the composite material in a real-world application, the team made a graphene-silver electrode (SPE/graphene-Ag) detector and compared it ...
