Micro Energy Harvesting for IoT Platform: Review Analysis Toward Future Research Opportunities — A Focus on Solar Energy Harvesting

The Internet of Things (IoT) requires sustainable, battery-free power solutions. Micro energy harvesting captures ambient energy to enable self‑powered IoT nodes. Among all available sources, solar energy (photovoltaic harvesting) offers the highest power density and greatest maturity, making it the most practical choice for indoor and outdoor IoT deployments.

Subcutaneous Micro Solar Cell with LED Patch: A Wirelessly Powered Implantable Sensor for Continuous Healthcare Monitoring

The micro solar cell harvests energy from ambient light, but its output drops sharply indoors or at night. To solve this, the LED patch – which attaches comfortably to the skin – emits red light (670 nm) that penetrates deeply through tissue, delivering reliable optical power to the subcutaneous solar cell. This hybrid approach ensures continuous, daylight‑independent energy supply.
