Internet of Things tagged posts

From Wi-Fi-connected home security systems to smart toilets, the so-called Internet of Things brings personalization and convenience to devices that help run homes. But with that comes tangled electrical cords or batteries that need to be replaced. Now, researchers reporting in ACS Applied Energy Materials have brought solar panel technology indoors to power smart devices. They show which photovoltaic (PV) systems work best under cool white LEDs, a common type of indoor lighting.

Indoor lighting differs from sunlight. Light bulbs are dimmer than the sun. Sunlight includes ultraviolet, infrared and visible light, whereas indoor lights typically shine light from a narrower region of the spectrum...

Researchers have developed a new fabrication method that makes tiny, thin-film electronic circuits peelable from a surface. The technique not only eliminates several manufacturing steps and the associated costs, but also allows any object to sense its environment or be controlled through the application of a high-tech sticker. Eventually, these stickers could also facilitate wireless communication. The researchers demonstrate capabilities on various objects in a paper recently published in the Proceedings of the National Academy of Sciences.

As society moves toward connecting all objects to the internet – even furniture and office supplies – ...

MIT Media Lab spinout Ori is developing smart robotic furniture that transforms into a bedroom, working or storage area, or large closet — or slides back against the wall — to optimize space in small apartments. Credit: Ori

Imagine living in a cramped studio apartment in a large city—but being able to summon your bed or closet through a mobile app, call forth your desk using voice command, or have everything retract at the push of a button. MIT Media Lab spinout Ori aims to make that type of robotic living a reality. The Boston-based startup is selling smart robotic furniture that transforms into a bedroom, working or storage area, or large closet—or slides back against the wall—to optimize space in small apartments.

Based on years of Media Lab work, Ori’s system is an L-shaped u...

Researchers from MIT’s Microsystems Technologies Laboratories (MTL) have designed a new power converter that maintains its efficiency at currents ranging from 100 picoamps to 1 milliamp, a span that encompasses a millionfold increase in current levels.

Design reduces converter’s resting power consumption by 50%. The “internet of things”, IoT is the idea that vehicles, appliances, civil structures, manufacturing equipment, and even livestock will soon have sensors that report information directly to networked servers, aiding with maintenance and the coordination of tasks. Those sensors will have to operate at very low powers, in order to extend battery life for months or make do with energy harvested from the environment...
