nergy-harvesting systems capture ambient energy from the environment and convert it into electrical signals to power electronic devices. Energy can be extracted from sources like light, heat, vibration, motion, radio waves and electromagnetic fields using specialised transducers. Tis harvested energy
can then be used to power devices immediately or store it in batteries for later use. Tese systems provide sustainable, self- sufficient power, reducing reliance on traditional power sources for applications such as wireless sensors, IoT devices, wearables and remote-monitoring devices.

to grow from $570m in 2023 to $918m by 2028, at a CAGR of 10%. This market is primarily driven by rising demand for clean and sustainable energy solutions and the increasing use of IoT devices and wireless sensors that require self-sustaining power sources in remote and challenging locations. These factors will continue to propel the growth of energy-harvesting systems in the coming years. Among the end-use systems in energy harvesting are:
Wireless switching systems Wireless switches convert energy from actuation, serving as a secondary power source for these devices, emergency switches and as controllers for starting and stopping machines. Wireless switching is ideal in situations where wiring is
impractical or the cost of wiring sensor networks is high. In wired sensor networks, batteries and wiring account for a
significant portion of the overall cost. Energy harvesting addresses this issue by serving as a primary energy source, collecting energy from sources like light, vibration or heat. In cases where more power is needed, the harvested energy can be stored in a secondary battery, which can then power wireless sensors; see Figures 1 and 2. Tis approach reduces costs, minimises maintenance needs and boosts system uptime.
Wireless HVAC systems Automation systems in commercial, residential and institutional facilities use sensors powered by energy-harvesting systems to monitor ambient parameters to optimise energy consumption. Piezoelectric and thermal-energy harvesters within heating, ventilation and air conditioning (HVAC) systems leverage airflow for energy production. Wireless HVAC systems in building control integrate
energy-harvesting technologies like miniature solar panels and thermoelectric generators into components like sensors and actuators. Tese devices operate autonomously, monitoring temperature, humidity and occupancy whilst controlling valves and fans for sustainable, real-time system optimisation. Te integration of energy harvesting addresses sustainability
