Hasta La Gadget!

Technologists have been drawing inspiration from the insect world for a long time. And folks working on robotics really seem to love their creepy-crawlies and buzzing arthropods. Researchers at the University of Illinois are looking to our eight-legged planet mates, not for mobility lessons, but as a reference for a new camera design. The system mimics the vision of bees and mantises by combining multiple lenses on a half hemisphere to provide a 180-degree view with a nearly infinite depth of field. The optics themselves are described as “soft, rubbery” and each individual microlens is paired with its own photodiode. The work gets us a heck of a lot closer to the dream of a digital fly eye than previous efforts, though we’re likely still quite a while from seeing applications outside of the lab. DARPA funding suggests the artificial compound eyes may have a future in surveillance, though the researchers also see uses for it in medicine.

Supercapacitors are often hailed as the holy grail of power supplies, but a group of researchers at the University of Illinois have developed a lithium-ion microbattery that leaves that prized solution in the dust, recharging 1,000 times faster than competing tech. Previous work done by Professor William P. King, who led the current effort, resulted in a fast-charging cathode with a 3D microstructure, and now the team has achieved a breakthrough by pairing it with an anode devised in a similar fashion.

The resulting battery is said to be the most powerful in the world, avoiding the usual trade-off between longevity and power while having a footprint of just a few millimeters. By altering its composition, scientists can even optimize the contraption for more juice or increased life. It’s expected that the technology could make devices 30 times smaller and help broadcast radio signals up to 30 times farther, but it’ll still be a while before it winds up in a super-slim phone within your pocket. For now, the researchers have their sights set on integrating the tech with other electronic components and investigating low-cost manufacturing.

MC10 might be best known for its wearable electronics aimed at athletes, but the company also makes a medical diagnostic sticker called a biostamp. Its creator (and MC10 co-founder), John Rogers has refined that design so that it’s no longer an elastomer sticker — now he can apply the biostamp’s thin, stretchy electronics directly on human skin, and bond it with commercially available spray-on bandage material. By losing the elastomer backing of the original biostamp and applying the circuits directly to the skin, Rogers and his team at the University of Illinois were able to shave the device’s thickness to 1/30th of the (already quite thin) biostamp. That super thin profile means it conforms even better to the contours of human hide and makes it shower- and swim-proof during the two weeks it lasts before being naturally exfoliated with your skin.

For those unfamiliar with what the biostamp does, it’s a mesh of circuits and sensors that can record electrophysiological data like skin temperature and hydration state of the wearer. The new biostamp won’t be in your doctor’s tool box any time soon, however, as Rogers and his team are still refining the wireless power and communication technologies it leverages. Of course, once those problems are solved, there’s a good chance we’ll see MC10 turning it into a commercial product.

While you’d be forgiven for not knowing who John Rogers is, he’s certainly graced these pages more than once. He’s the research chief at the University of Illinois that’s previously broken new ground in the world of invisibility cloaks and wearable technology. This time, his team has cooked up a silicon, magnesium, magnesium oxide and silk circuit that’s designed to dissolve in the body in the same way that absorbable sutures are used in minor surgeries. It’s thought that the tech could eventually be used to implant monitors that never need removal, reducing invasive medical procedures, or even build devices that eventually turn into compost rather than E-waste — although we’re not sure we’d appreciate our smartphone doing the same thing when we’re making calls in the rain.
