The Secret Lives of Miniature Batteries

Blog Article

This article describes the design, implementation, and use of a new system to investigate the behavior of small batteries that power sensor and wireless systems that consume relatively high power during infrequent short activity periods.The system enables simple, low-cost, long-term (days to weeks) monitoring of batteries under such loads.Data collected ethical nutrients mega magnesium powder citrus 450g by this system revealed a major cause of failures in wildlife tracking tags, an effect called concentration polarization, which rumchata proof causes a transient increase in the internal resistance of the battery.

The article describes the goals and the design of the system, failures that it revealed, mechanisms to mitigate the limitations of miniature batteries, as well as a methodology to optimize and validate the design of tags powered by miniature batteries.
