RA-L 2025
Capsule endoscopy and drug delivery hold great promise but are constrained by power supply limitations. This study introduces a battery-free capsule robot powered by wireless power transfer (WPT), utilizing a phase-controlled 2D planar array operating at 6.78 MHz. This setup provides a stable energy
