Figure 4From: On the viability of implantable electrodes for the natural control of artificial limbs: Review and discussion Cuff electrode. Cuff electrode with circumferential (A, B, D and E) and discrete (C) contacts with possible differential configurations in bipolar (1), tripolar (2) [46] and short-circuit tripolar (3) [47]. In the latter configuration, the outer electrode pair is short-circuited in order to yield a screening effect [47].Back to article page
