KAIST Develops a Venus Flytrap-Inspired ‘Robot Hand’ Material That Senses Objects and Grasps Them Under Light (IMAGE)
Caption
Figure 2. Sensing performance and operation of the bioinspired Ionograsper.
(a) How ions inside the material rearrange and produce a voltage as a charged object approaches and moves away. (b) Simulation of the electric potential distribution at different distances from the object. (c) Change in open-circuit voltage with distance from the object. (d) Voltage signals when the object moves back and forth at different frequencies. (e) Sensing signals as the object approaches, stays still, and moves away. (f) Voltage signals as the object approaches and is grasped. (g) The Ionograsper senses an object, moves when UV light is applied, holds the object, and then releases it.
