A dual-band wireless neural stimulation device with high frequency (HF) wireless power transfer (WPT) at 13.56MHz and ultra high frequency (UHF) backscatter communication (BSC) at 915MHz is presented. Neural interfaces hold great promise in the development of future treatment/therapy for debilitating neurological disorders, spinal cord damage, and loss of limb function. Most state-of-the-art wireless...
Pretouch sensing is longer range than contact, but shorter range than vision. The hypothesis motivating this work is that closed loop feedback based on short range but non-contact measurements can improve the reliability of manipulation. This paper presents a grasping system that is guided at short range by Electric Field (EF) Pretouch. We describe two sets of experiments. The first set of experiments...
We describe a robot that is able to autonomously plug itself in to standard, unmodified electrical outlets by sensing the 60Hz electric fields emitted from the outlet. The building electrical infrastructure is not modified in any way. Unlike previous powerline localization work, no additional signal is injected in the powerlines-the already present AC power carrier signal in the outlet is used as...
