Inside the Partnership
Exeger and EM Microelectronic have a longstanding collaboration focused on advancing energy-efficient consumer electronics and Internet of Things (IoT) devices. By combining Exeger’s solar cell technology, Powerfoyle, with EM Microelectronic’s ultra-low power IC expertise, the partnership delivers tailored energy harvesting systems – enabling the next generation of self-powered products.
Together, the two companies have developed a highly integrated plug-and-play solution designed to unlock the full potential of Powerfoyle in real-world consumer applications. At its core is an energy harvesting chip from EM Microelectronic, specifically optimized for Powerfoyle’s unique characteristics – delivering efficient energy harvesting even in ultra-low light conditions, down to the microwatt range. The combined solution represents a breakthrough in batteryless smart devices, offering designers a fully optimized, scalable energy harvesting solution that delivers both performance and design flexibility.
In December 2024, Exeger transferred its boost converter business to EM Microelectronic. This strategic move allows Exeger to focus fully on scaling the production and adoption of Powerfoyle, while EM takes over direct responsibility for the boost converter technology. As the original developer and manufacturer of the underlying chip, EM is ideally positioned to advance the technology further and support its integration across a wide range of consumer and industrial devices.
“Exeger have developed an excellent boost IC with us, and we look forward to developing it further with our world-class expertise and resources. The very impressive customer pipeline for both the Powerfoyle Indoor and Hybrid platforms is at the core of this decision to take over Exeger’s business and further develop it directly. We are excited about the business perspectives for both our companies in this field, and we are confident this cooperation will lead to new, highly-competitive and innovative products and applications, in line with our vision for environmentally-friendlier, ambient light-powered devices.”
