New Flexible Electronics Research Shows Promise for Spinal Therapies

Patients recovering from spinal cord injuries or who have mobility disorders related to spinal nerve compression are frequently treated by the conditioning of the Hoffmann's reflex via non-surgical electrostimulation therapy. To track the progress of the treatment, electromyography is used to record the amplitude of the patient's muscle twitch response.

Hyper-Efficient Conservation Robot

For the next several months, visitors to the Atlanta Botanical Garden will be able to observe the testing of a new high-tech tool in the battle to save some of the world's most endangered species. SlothBot, a slow-moving and energy-efficient robot that can linger in the trees to monitor animals, plants, and the environment below, will be tested near the Garden's popular Canopy Walk.

mmWave electronics: towards AiP (antenna-in-package) technologies

Electronic packaging will play an important role in enabling higher frequency - e.g., mmWave - electronics. In particular, as the frequency goes up, the antenna spacing shrinks, the need to have large antenna arrays for gain as well as beam forming purposes increases; and the imperative to cut down transmission loss including by placing components closer together inside a package dramatically grows

Lung-Heart Super Sensor on a Chip Tinier Than a Ladybug

During a stroll, a woman's breathing becomes a slight bit shallower, and a monitor in her clothing alerts her to get a telemedicine check-up. A new study details how a sensor chip smaller than a ladybug records multiple lung and heart signals along with body movements and could enable such a future socially distanced health monitor.

Harnessing Hot Carriers for High Efficiency Solar Cells

Two-dimensional solar materials may offer a way to extract more energy from sunlight. By tuning the structure of a 2D perovskite solar material, researchers have shown they can prolong the lifetime of highly energetic hot carriers generated by light striking the material. The approach could offer a way to capture solar energy more efficiently.

Storing Medical Information Below the Skin's Surface

Every year, a lack of vaccination leads to about 1.5 million preventable deaths, primarily in developing nations. One factor that makes vaccination campaigns in those nations more difficult is that there is little infrastructure for storing medical records, so there's often no easy way to determine who needs a particular vaccine.

Perovskite Nanocrystals More Durable with Plastic Hair and Silica

Perovskite nanocrystals hold promise for improving a wide variety of optoelectronic devices - from lasers to light emitting diodes - but problems with their durability still limit the material's broad commercial use.

Novel Solar Cells Arrive at International Space Station for Testing

Five different types of solar cells have arrived at the International Space Station to be tested for their power conversion rate and ability to operate in the harsh space environment as part of the MISSE-12 mission. One type of cell, made of low-cost organic materials, has not been extensively tested in space before.

Shape-shifting robots built from 'smarticles'

Building conventional robots typically requires carefully combining components like motors, batteries, actuators, body segments, legs and wheels. Now, researchers have taken a new approach, building a robot entirely from smaller robots known as "smarticles" to unlock the principles of a potentially new locomotion technique.

Wearable brain-machine interface could control a vehicle, computer

Combining new classes of nanomembrane electrodes with flexible electronics and a deep learning algorithm could help disabled people wirelessly control an electric wheelchair, interact with a computer or operate a small robotic vehicle without donning a bulky hair-electrode cap or contending with wires.

Stretchy plastic electrolytes for new lithium-ion battery design

The growing popularity of lithium-ion batteries in recent years has put a strain on the world's supply of cobalt and nickel - two metals integral to current battery designs - and sent prices surging. In a bid to develop alternative designs for lithium-based batteries with less reliance on those scarce metals, researchers have developed a promising new cathode and electrolyte system that replaces expensive metals and traditional liquid electrolyte with lower cost transition metal fluorides and a solid polymer electrolyte.

Stretchable wireless sensor could monitor healing of cerebral aneurysm

A wireless sensor small enough to be implanted in the blood vessels of the human brain could help clinicians evaluate the healing of aneurysms -- bulges that can cause death or serious injury if they burst. The stretchable sensor, which operates without batteries, would be wrapped around stents or diverters implanted to control blood flow in vessels affected by the aneurysms.

Tiny vibration-powered robots are the size of the world's smallest ant

Researchers have created a new type of tiny 3D-printed robot that moves by harnessing vibration from piezoelectric actuators, ultrasound sources or even tiny speakers. Swarms of these "micro-bristle-bots" might work together to sense environmental changes, move materials - or perhaps one day repair injuries inside the human body.

Tiny supersonic jet injection for nanoscale additive manufacturing

By energizing precursor molecules using a tiny, high-energy supersonic jet of inert gas, researchers have dramatically accelerated the fabrication of nanometer scale structures. The rapid additive manufacturing technique also allows them to produce structures with high aspect ratios. Now, a theory developed to describe the technique could lead to new applications for additive nanomanufacturing and new nanoscale materials.
