Which products can be powered by light energy harvesting?

Light energy harvesting enables a wide range of low-power electronics to operate using ambient indoor light. 

These energy harvesting applications span multiple industries: 

Consumer electronics 
Self-charging remote controls (RCU), in-ear devices, keyboards, and computer mice. 

Retail 
Electronic shelf labels (ESL) and visual displays.  

Logistics 
Asset trackers and connected devices for tracking and monitoring goods. 

Smart buildings / IoT 
Wireless sensors, access cards, digital locks, and smoke detectors. 

These applications of energy harvesting reduce the need for battery replacement and enable scalable, maintenance-free systems.
