We estimate that low power energy harvesting MCUs market will cross half a billion dollar mark by 2025
Currently, the low and ultra-low power microcontrollers are being used in all the industries owing to the need to higher battery life for consumer electronics product. However, there are very few instances of the use of energy harvesting technology in consumer electronics industry. By 2025, more than 100 million low power energy harvesting MCUs will be sold in various applications such as wearable devices, medical and healthcare devices, smart homes devices, precision agriculture devices. The growth will be driven with the introduction of 5G connectivity solutions, wireless sensor networks, wireless sensor hubs, security networks, Internet of Things especially in industrial applications.
Energy harvesting (EH) technology scavenges energy from one or more of naturally-occurring sources such as solar, thermal, kinetic, and vibration. The most promising technologies for harvesting energy from these sources are photovoltaic materials (for solar energy) piezoelectric materials (for mechanical energy) and thermoelectric/pyroelectric materials (for thermal energy).
The technology has been used for decades at macro levels however, recently the technology is spreading to more and more application areas particularly in applications such as wearable devices, smart homes, medical devices, smart agriculture, smartphones, and wireless sensor networks, among others. Wearable devices applications is currently a lead markets for the application of energy harvesting. In coming 5 – 7 years, the wireless sensor networks for smart homes, smart agriculture, building and home automation, and IoT will be the fastest growing markets for energy harvesting technology.
