In a bid to solve power supply issues due to the spread and advancement of IoT devices, Sony Semiconductor Solutions Corporation (SSS) has developed a module for energy harvesting that efficiently generates electricity from electromagnetic noise energy.
With the help of electromagnetic noise produced by any piece of electrically powered machinery, this newly invented device may generate electricity. Research is growing in areas including radio waves, light, heat, and vibration for energy harvesting, a technology that supports the growth of an IoT society and a sustainable global environment.
“With the spread and sophistication of IoT devices, the problem of power supply to the increasing number of IoT devices is attracting attention, said Sony.” In addition to being highly effective, this technology is an energy-harvesting technology that is expected to have a wide range of applications. We aim to contribute to the development of a sustainable IoT society.”
Based on the antenna technology that the company has established through tuner development, this created product uses the metal components of electronic gadgets, which are sources of electromagnetic noise, as part of the antenna.
Adopts a special design with a rectifier circuit to boost conversion effectiveness. As a result, despite being a small module, it transforms electromagnetic noise in the few Hz to 100 MHz band into electrical energy, enabling the powering and charging of batteries as well as low-power IoT sensors and communication devices.
The industry’s first harvesting technique it produces electricity with a high level of efficiency. It is conceivable to sustainably supply power to fulfill the power consumption required by IoT sensors and other devices by successfully using electromagnetic noise, which has not previously garnered attention, as a new power source.
In addition, by miniaturizing the module, we have increased the flexibility of installation by lowering the amount of components that make up the module.
Additionally, as long as the electronic equipment is powered on, electricity may be harvested even while it is in standby mode. As a result, it can be used in a variety of indoor and outdoor applications, including factories, offices, stores, and houses.
