TL;DR: A new design for an energy harvesting device is proposed in this paper, which enables scavenging energy from radiofrequency (RF) electromagnetic waves by proposing a dual-stage energy harvesting circuit composed of a seven-stage and ten-stage design, the former being more receptive in the low input power regions, while the latter is more suitable for higher power range.

TL;DR: This paper demonstrates an adjustable circuit for harvesting from LTE 700-MHz, GSM 850- MHz, and ISM 900-MHz bands with one single circuit, fabricated on printed circuit board with comprehensive evaluations at each associated frequency to test the power conversion efficiency (PCE).

TL;DR: A wrist muscles-to-gesture model is built, based on which a hand gesture classification method using both motion and static features is developed, and a kernel-based on-wrist localization technique to detect the CapBand's position on the user's wrist is proposed.

TL;DR: A rigorous analytical model based on galvanic coupling of low energy signals is developed for enabling communication between sensors and actuators embedded within the tissue, or placed on the surface of the skin, pointing to the suitability of the model for quick and accurate channel characterization and parameter estimation for networked and implanted sensors.

TL;DR: In this paper, the authors developed a suite of analytical expressions for modeling the resulting communication channel for weak electrical signals in a three dimensional multi-layered tissue structure, validating and verifying the model through extensive finite element simulations, published measurements in existing literature, and experiments conducted with porcine tissue.
