Tumbling Magnetic Microrobots for Targeted In Vivo Drug Delivery in the GI Tract

Advanced Robotics Research, EarlyView.
We introduce a microrobot design and integrated system for on‐demand targeted drug release in the gastrointestinal tract. The microrobot has an embedded magnet for actuation with external magnetic fields and is visualized in real time using ultrasound. It has two drug release ports sealed with a thermally sensitive wax. Local heating of the wax using a

PERMEABILITY AND ENVIRONMENTAL ENCLOSURE

Perceptual and Motor Skills, 2003
Theories by J. J. Gibson and H. Hediger suggest that environmental enclosure is important. Re-examination of their work suggests that judged degree of enclosure might be influenced by permeability of spatial regions. This study reports effects on judgments of enclosure by permeability and two other factors, horizontal size of rooms and heights of walls.
