Silicon Anodes Muscle in on Battery Technology

Silicon is a staple of the digital revolution, shunting loads of signals on a device that's likely just inches from your eyes at this very moment. Now, that same plentiful, cheap material is becoming a serious candidate for a big role in the burgeoning battery business. It's especially attractive because it's able to hold 10 times as much energy in an important part of a battery, the anode, than widely used graphite.

New Printing Technique for Flexible Electronics

New technology that enables more efficient and effective transfer printing for electronic devices has been developed by researchers

Prototype Robotic Device Picks and Trims Button Mushrooms

Researchers have developed a robotic mechanism for mushroom picking and trimming and demonstrated its effectiveness for the automated harvesting of button mushrooms.

Transparent Electrode Boosts Solar Cell Efficiency

Developing new ultrathin metal electrodes has allowed researchers to create semitransparent perovskite solar cells that are highly efficient and can be coupled with traditional silicon cells to greatly boost the performance of both devices, said an international team of scientists. The research represents a step toward developing completely transparent solar cells.

Skin and Bones Repaired by Bioprinting During Surgery

Fixing traumatic injuries to the skin and bones of the face and skull is difficult because of the many layers of different types of tissues involved, but now, researchers have repaired such defects in a rat model using bioprinting during surgery, and their work may lead to faster and better methods of healing skin and bones.

Stretching the Boundaries of Medical Tech with Wearable Antennae

Current research on flexible electronics is paving the way for wireless sensors that can be worn on the body and collect a variety of medical data. But where do the data go? Without a similar flexible transmitting device, these sensors would require wired connections to transmit health data.

Deep Learning Improves Air Quality Forecasts

Air pollution from the burning of fossil fuels impacts human health but predicting pollution levels at a given time and place remains challenging, according to a team of scientists who are turning to deep learning to improve air quality estimates.

Harvesting Energy from Radio Waves to Power Wearable Devices

From microwave ovens to Wi-Fi connections, the radio waves that permeate the environment are not just signals of energy consumed but are also sources of energy themselves.

Inexpensive Tin Packs a Punch for Future Supercapacitors

A sustainable, powerful micro-supercapacitor may be on the horizon. Until now, the high-capacity, fast-charging energy storage devices have been limited by the composition of their electrodes — the connections responsible for managing the flow of electrons during charging and dispensing energy. Now, researchers have developed a better material to improve connectivity while maintaining recyclability and low cost.

Implant Improves Quality of Life for People with Inner Ear Disorder

Researchers have shown that they can facilitate walking, relieve dizziness and improve quality of life in patients with inner ear disorder by surgically implanting a stimulator that electrically bypasses malfunctioning areas of the inner ear and partially restores the sensation of balance.

Wearable Sensor Monitors Health, Administers Drugs Using Saliva, Tears

A new kind of wearable health device would deliver real-time medical data to those with eye or mouth diseases.

Inexpensive Battery Charges Rapidly for Electric Vehicles

Range anxiety, the fear of running out of power before being able to recharge an electric vehicle, may be a thing of the past, according to a team of engineers who are looking at lithium iron phosphate batteries that have a range of 250 miles with the ability to charge in 10 minutes.

Stretchable Micro-Supercapacitors to Self-Power Wearable Devices

An alternative to batteries, micro-supercapacitors are energy storage devices that can complement or replace lithium-ion batteries in wearable devices. Micro-supercapacitors have a small footprint, high power density, and the ability to charge and discharge quickly.

Smart Wrap Implant may Help Bladder Control

An implantable smart wrap that fits safely and securely around the bladder may one day help people who have under-active bladders, a condition that hinders patients from urinating regularly and comfortably, according to an international team of researchers.

New Tool can Diagnose Strokes with a Smartphone

A new tool created by researchers could diagnose a stroke based on abnormalities in a patient's speech ability and facial muscular movements, and with the accuracy of an emergency room physician -- all within minutes from an interaction with a smartphone.

Treeswift's Autonomous Robots Take Flight to Save Forests

Forests cover 30% of the Earth's landmass, but that number is on the decline. Despite forests' crucial role in conserving wildlife and processing carbon dioxide, many are threatened by deforestation and wildfires. Complicating these threats is the lack of quantitative information that foresters and environmental researchers need for making important decisions to preserve forests.

AI Keeps an Eye on Volcano Movements

Radar satellites can collect massive amounts of remote sensing data that can detect ground movements at volcanoes in near real time. These ground movements could signal impending volcanic activity and unrest; however, clouds and other atmospheric and instrumental disturbances can introduce significant errors in those ground movement measurements. Now, researchers have used artificial intelligence to clear up that noise, drastically facilitating and improving near real-time observation of volcanic movements and the detection of volcanic activity and unrest.

Engineers Print Wearable Sensors Directly on Skin Without Heat

Wearable sensors are evolving from watches and electrodes to bendable devices that provide far more precise biometric measurements and comfort for users. Now, an international team of researchers has taken the evolution one step further by printing sensors directly on human skin without the use of heat.

Using Wearable Technology to Prevent Kidney Stones

Kidney stones are a painful and expensive medical problem, and people who suffer from kidney stones once are likely to experience them a second time. Recurrence can often be prevented if patients increase urine output by increasing the amount of water that they drink. Though this may seem easy, fewer than 50% of people who have suffered from kidney stones are able to drink the recommended amount of fluids.
