Electrolytic Silicone Bourdon Tube Actuator




The Electrolytically Actuated Silicone Bourdon Tube was developed as part of a pilot study on actuation strategies for very small robots. The study was carried out at the CRIM laboratory at SSSA, Italy, and was part of a larger ongoing effort at CRIM to create Assemblable Reconfigurable Endoluminal Surgical Robots (ARES). Electrolysis was found to be a surprisingly low-power actuation strategy if speed is not essential. In the GI tract, the hydrogen and oxygen produced can be safely vented at the end of an actuator cycle.
