Digitization often starts by interfacing to the real world with sensors and smart devices. Providing billions of devices with electrical energy is one of the big challenges of a growing internet of things. The need for frequent replacement of batteries or labour- and cost-intensive wiring is not only a significant cost factor. The constraints in energy supply can also be a show-stopper for implementing new solutions. As a result, a large potential of the internet of things remains untapped. Light is often an abundant source of energy – not only outdoors, but also indoors. Enerthing has developed the next generation photovoltaic film which can outperform batteries. Based on our core technology, we bring asset-tracking, indoor navigation and sensing in buildings to the next level combining high performance, maintenance-free operation and sustainability. With our broad expertise ranging from manufacturing of high performance customizable photovoltaic films, energy efficient hardware and software systems design we develop new IoT solutions which push the boundaries of today’s battery powered and cable tied IoT world.
