By replacing the phosphor screen in a laser phosphor display (LPD) with a luminescent solar concentrator (LSC), one can harvest energy from ambient light as well as display high-resolution images. “Energy-harvesting laser phosphor display and its design considerations”, published recently by SPIE, the international society for optics and photonics, in the Journal of Photonics for Energy, […]
Autonomous energy-scavenging micro devices will test water quality, monitor bridges, more
BELLINGHAM, Washington, USA — Out in the wilds or anywhere off the grid, sophisticated instruments small enough to fit in a shirt pocket will one day scavenge power from sunlight, body heat, or other sources to monitor water quality or bridge safety, enabling analysis in the field rather than bringing samples and data back to […]
