Ultrakompakt solcelle-baseret energy harvesting til wearables og IoT-enheder

Maxim introducerer MAX20361, der er en solcelle-baseret energy harvesting enhed, som på en gang fylder markant mindre og er mere effektiv end eksisterende løsninger (in english).

Designers of space-constrained designs can now significantly increase runtime with the MAX20361 single-/multi-cell solar harvester with maximum power point tracking (MPPT) from Maxim Integrated Products. The industry’s smallest solar harvesting solution is ideal for space-constrained applications such as wearables and emerging internet of things (IoT) applications.

Designers are often challenged with the tradeoff between small size and long runtime for wearable and IoT applications. By enabling solar charging in these highly space-constrained products, the MAX20361 can extend the runtime of those devices by providing a supplemental power source.


This solar harvester reduces solution size by at least half compared to the closest competitor, according to Maxim. In addition, the MAX20361 increases harvested energy with up to 5 percent better boost efficiency than the closest competitor, coupled with an adaptive MPPT approach which can improve the overall system level efficiency even further.

- This device offers exciting possibilities for a new supplemental power source to continually charge the battery of a device, says Frank Dowling, director of the Industrial and Healthcare Business Unit at Maxim Integrated.
- For example, if you can harvest just 30mW of solar power per day on a 300mAh battery system which typically runs for three weeks, you can as a result extend that runtime by over 50 percent. 

- Innovation continues to drive adoption of consumer wearables with global revenue estimated to grow at a compound annual growth rate (CAGR) of 15 percent in the next four years, adds James Hayward, principal analyst at IDTechEx Research.
- For device manufacturers, longer battery life and smaller form factor remain key product features toward market differentiation and user satisfaction.
