Wearable and IoT devices increasingly use high-rate sensors such as IMUs, microphones, and cameras that operate at ultra-low power budgets between tens of microwatts and a few milliwatts in always-on mode. But these always-on rich sensors generate a huge amount of data which stresses the communication and computation capabilities of resource-limited sensor devices, particularly when used in real-time scenarios. I will describe our work on communication and computation building blocks to tackle this problem. On the communication side, I will describe ultra-low power radios that rely on combination of active and passive components to enable continuous communication of rich sensor data while operating at tens of microwatts of power. On the computation side, I will describe how we can leverage low-power neural accelerators and low-power communication to enable energy-efficient execution of deep learning models.
