Chemical Power for Swarms of Microscopic Robots in Blood Vessels
Tad Hogg
Microscopic robots in the bloodstream could obtain power from fuel cells using glucose and oxygen. Previous studies of small numbers of such robots operating near each other showed…
Acoustic Power Management by Swarms of Microscopic Robots
Tad Hogg
Microscopic robots in the body could harvest energy from ultrasound to provide on-board control of autonomous behaviors such as measuring and communicating diagnostic information a…
Identifying Vessel Branching from Fluid Stresses on Microscopic Robots
Tad Hogg
Objects moving in fluids experience patterns of stress on their surfaces determined by the geometry of nearby boundaries. Flows at low Reynolds number, as occur in microscopic vess…
Stress-Based Navigation for Microscopic Robots in Viscous Fluids
Tad Hogg
Objects moving in fluids experience patterns of stress on their surfaces determined by their motion and the geometry of nearby boundaries. Fish and underwater robots can use these…
Energy Dissipation by Metamorphic Micro-Robots in Viscous Fluids
Tad Hogg
Microscopic robots could perform tasks with high spatial precision, such as acting on precisely-targeted cells in biological tissues. Some tasks may benefit from robots that change…
Using Surface-Motions for Locomotion of Microscopic Robots in Viscous Fluids
Tad Hogg
Microscopic robots could perform tasks with high spatial precision, such as acting in biological tissues on the scale of individual cells, provided they can reach precise locations…
