Power Management System for Online Low Power RF Energy Harvesting Optimization
TL;DR: A “smart” microcontroller-based power management system with online power stage efficiency optimization and maximum power point tracking (MPPT) is presented, experimentally evaluated using a new, more accurate four-quadrant rectenna model and circuit realization.

TL;DR: In this article, a distributed array of antennas with optimized power management circuits is introduced to increase harvested power and efficiency for low-power density incident plane waves for electronic devices in environments where it is difficult or impossible to change batteries and where the exact locations of the energy sources are not known.
Journal ArticleDOI
Integration of Frequency Response Measurement Capabilities in Digital Controllers for DC–DC Converters
TL;DR: In this paper, the authors demonstrate the feasibility of incorporating fully automated frequency response measurement capabilities in digital PWM controllers at relatively low additional cost using a Verilog-coded implementation with low tens of thousands of logic gates and about 10 kB of memory.
Proceedings ArticleDOI
Wirelessly-Powered Wireless Sensor Platform
TL;DR: A low-power 2.45-GHz wireless sensor platform consisting of a three-axis accelerometer, thermometer and skin conductivity sensor intended for low-maintenance assistive technology, elder-care and medical applications is presented.
Proceedings ArticleDOI
Online Health Monitoring in Digitally Controlled Power Converters
TL;DR: In this article, the authors focus on two aspects of power converter health monitoring: detecting and analyzing loss-related and frequency response-related changes, which can be implemented without any additional sensing points other than those required for operation of the converter and with minimal additional digital hardware.
