Abstract
Sustainable development and cognitive capabilities are critical for maximizing energy efficiency. Electricity circuit management should be environmentally friendly across all the power options, ranging from nanowatts (nW) during sleep modes to milliwatts (mW) during active operation. This work presents an adaptable, firmware-configurable electrical power module that enables intelligent devices to operate in the sub-µW range, promoting sustainability through energy harvesting. The microcontroller-based design efficiently converts energy from rechargeable batteries, environmental DC and AC sources, and static currents. Multiple DC-DC converters separate the energy source and the load points, providing adaptive voltage scaling to loads while maintaining high reliability. The experimental results illustrate the flexibility and the efficiency of the strategy above. Specifically, the proposed power supply module attains a static current of 54 nA and a maximum load current of 300 mA, achieving an end-to-end energy efficiency that exceeds 95%. Intelligent lighting applications monitor and regulate networked systems, enhancing reliability, facilitating cost savings, and improving efficiency. A foundational smart module has been developed to integrate with streetlight setups, enabling simultaneous control and evaluation of lamp parameters. The findings substantiate that the proposed smart device is both efficient and flexible, in addition to demonstrating compatibility. The circuit supports software-configurable power control, achieving static currents of 35 nA and 640 nA with active energy harvesting. It efficiently supplies loads with unpredictable power requirements and compares duty cycling and event-driven techniques.
