Our proposed harvester design addresses several fundamental questions related to low-frequency mechanical-to-electrical conversion process such as: ?How to convert semi-periodic vibrations in to useful electricity with near ideal efficiencies??, ?How to tune the harvester to obtain wide bandwidth such that the same device operates in multiple frequency bands??, and ...

Energy Harvesting has become of priority importance for powering up remote electronics that might be difficult to access, for example in the case of Structrural Health Monitoring devices or data collection sensors and sensor networks. The purpose of the proposed invention aims at efficiently harvesting energy from rain for ...

Energy Harvesting has become of priority importance for powering up remote electronics that might be difficult to access, for example in the case of Structrural Health Monitoring devices or data collection sensors and sensor networks. The purpose of the proposed invention aims at efficiently harvesting energy from wind for ...

This technology uses a piezo-magneto-elastic device for substantial performance enhancement in broadband vibration energy harvesting. The prototype tested in our lab exhibits large-amplitude periodic (limit cycle) oscillations for excitations over a frequency range. The piezo-magneto-elastic generator results in a 200% increase in the open-circuit voltage amplitude (hence promising ...

A modular portable windmill was designed with conatiner bottle that can be assembled on-spot to provide electrical power in the range of 130 mW. The whole windmill fits inside a nalgene bottle and can be assembled in less than 2 mts. The windmill is designed to be an plug-n-play device ...
