C1.1 Energy autonomy and energy awarenessWe will perform research on specific needs for all distributed sensors (from areas A and B) creating a number of innovations for embedded autonomous sensor systems. All sensors will be equipped with ultra-low power electronics and communication capabilities to go beyond their pure sensing function, and to enable them as active and intelligent sensor nodes in our ECOSENSE network. Self-test features and energy awareness will be incorporated to improve a sensor node’s performance over time. C1.2 Ultra-low power and long-range radiosWireless communication between individual sensor nodes and central sensor hubs will be provided, by using newly established communication networks (e.g. narrow-band Internet-of-Things or NB-IoT), as well as specially tailored low-power local radio (e.g. LoRa). The energy supply of such widely distributed sensor nodes has to happen either via energy harvesting from thermal, solar, or mechanical ambient energy, or via passive remote sensing approaches similar to today’s RFID technology.
