Rapid Growth in the Internet of Things is Threatened due to the Energy Challenge

Today, most of the Internet of Thing (IoT) devices are energy-expensive and powered by bulky batteries with limited lifespans. Replacing (frequently) batteries on potentially a trillion IoT device deployed in the wild represents a significant challenge. It can limit the large-scale deployment of IoT devices and prevent us from unlocking the massive economic value enabled through the use of IoT.
IoT devices have a pipelined architecture where a physical phenomenon is sensed, processed, and communicated to a powerful edge or a gateway device through a series of steps. This architecture has largely remained unchanged over the past two decades. However, during this time, the individual components that make up this architecture demonstrate a significant energy asymmetry (energy-expensive components are shown in red). Radio or communication module consumes the most energy.
