Abstract :
Sensor nodes are used extensively in order to gather real-time information in the social environment and natural environment. And the production volume of sensor nodes is much increased with the development of cyber-physical systems. Therefore, it becomes important how to reduce the power consumption of huge sensor nodes. In this work, normally-off architecture of microcontroller for future low-power sensor node is proposed. To realize true low-power effects with normally-off computing technology, a co-design of hardware and software technology is much important. In this work, the power consumption of sensor nodes is possible to reduce of around 70% by using normally-off MCU architecture in sensor node.
