Using energy harvesting, radio technologies to power wireless sensors

Gathering data from wireless sensors is critical in the Industrial Internet of Things (IIoT) era; using energy harvesting and radio frequency identification (RFID) can provide peace of mind for operators who don’t have to worry about batteries.

Focused laser light generates an optical “tractor beam,” which can manipulate and orient semiconductor nanorods (red) with metal tips (blue) in an organic solvent solution. The energy from the laser superheats the metallic tip of the trapped nanorod, allowing the aligned nanorods to be welded together end-to-end in a solution-based “nanosoldering” process.

A key to compiling the novel Omnipush dataset was building modular objects (pictured) that enabled the robotic system to capture a vast diversity of pushing behavior. The central pieces contain markers on their centers and points so a motion-detection system can detect their position within a millimeter. Courtesy: Massachusetts Institute of Technology (MIT)
