Abstract
-
Electrotactile stimulation is a highly promising technique for providing sensory feedback
information for prosthetics. To this aim, disposable electrodes which are predominantly
used result in a high environmental and financial cost when used over a long period
of time. In addition, disposable electrodes are limited in their size and configurations.
This paper presents an alternative approach based on a 3D printed reusable
flexible concentric electrode coated with a conductive graphene ink. Here, we have
characterized the electrode and demonstrated its effective performance in electrotactile
stimulation and sensory feedback for robotic prosthetic hands.
