The interest for developing smart systems based on interconnected objects is growing fast (50 billion objects connected in 2020).

The main components of “Internet of Things” (IoT) devices are autonomous battery-operated smart embedded systems comprising communication circuits, sensors, computing/processing devices and storage. The key requirements are ultra-low power, high processing capabilities, fast/dense storage, wireless communication, heterogeneous integration, and autonomy. The different functions are so far implemented in separate chips/technologies, which is a bottleneck in terms of costs and miniaturization.
