Controlling a Gut Bot’s Position
July 31, 2008 | Source: Technology Review
Carnegie Mellon University researchers have developed a tiny capsule robot adhesive enough to anchor inside an intestine and yet gentle enough not to tear soft tissue.
They looked to beetles, which secrete oil-like liquids along their foot hairs to stick securely to surfaces, and coated the robot’s feet with a similarly viscous liquid for more adhesion, using a surface-tension component.
Future possible uses include biopsy and control of bleeding.
