CLEAN-Boost® Solution

CLEAN-Boost® technology is utilized for wireless transmission and other electrical energy. It makes use of minute energy which has conventionally been discarded until now, as well as our original storage and boosting technology , which we have researched and developed over many years.
CLEAN-Boost® uses electricty from sunlight, body heat, vibrations, and other natural phenomena as energy. This technology will help to facilitate IoT cloud services that are simple to set up and require no battery changes.
