One of the strongest growing areas of the digitization revolution is the internet of things (IoT). The dependence on electrical energy imposes a significant limitation on development of new IoT applications. Our flexible photovoltaic films open up new possibilities, for example in the areas of asset tracking and indoor navigation


High conversion efficiency under artificial illumination

Enerthing’s photovoltaic technology is optimized for converting artificial (indoor) light into electricity. It is highly efficient and allows for the autonomous operation of various IoT devices equipped with transmitters, receivers and sensors. The big advantage is the removal of the requirement to regularly change batteries. By tailoring the device to the application our energy harvesting solution can extract more power from ambient light than commonly used batteries can provide over a limited period of a few years. The gain in power can be translated in a gain in performance, e.g. higher data rate, more measurements, better quality of data.


Maintenance-free and scalable IoT-Solutions

In collaboration with partners, we are developing maintenance-free, and therefore scalable applications, for asset tracking and indoor navigation. IoT-devices have to be maintenance-free if several hundred or thousand individual objects are equipped with radio transmitters and sensors. Our solution will enable applications which previously had to be ruled out due to battery replacement on a large scale being neither economical nor sustainable.
