Flexible, High-Performance Transparent Electrodes
The future of electronic displays will be thin, flexible and durable. One barrier to this, however, is that one of the most widely used transparent conductors for electronic displays—indium tin oxide —doesn't perform as well on larger areas and can crack and break down with wear.

New Possibilities for 3D-Printing Human Tissue, Vocal Chord Repair
There is no replacement for the vocal cords when damage is severe or permanent. Now, a team of materials scientists has developed a soft material with promise of new treatments in the future. Their novel soft material, called an elastomer, is very stretchable and 10,000 times softer than a conventional rubber, matching the mechanical properties of vocal cords. The elastomer can be 3D printed for use in health care.

Personalized Sweat Sensor Reliably Monitors Blood Glucose
Many people with diabetes endure multiple, painful finger pricks each day to measure their blood glucose. Now, researchers have developed a device that can measure glucose in sweat with the touch of a fingertip, and then a personalized algorithm provides an accurate estimate of blood glucose levels.

Uncrackable Combination of Invisible Ink and Artificial Intelligence
Coded messages in invisible ink sound like something only found in espionage books, but in real life, they can have important security purposes. Yet, they can be cracked if their encryption is predictable. Now, researchers have printed complexly encoded data with normal ink and a carbon nanoparticle-based invisible ink, requiring both UV light and a computer that has been taught the code to reveal the correct messages.

18.6% Efficiency Near Infrared Transparent Perovskite Solar Cell
Researchers have realized a 18.6% efficient highly near infrared transparent perovskite solar cell. When combined in a four terminal tandem configuration with an efficient Panasonic crystalline silicon (c-Si) cell or with a Miasolé flexible CIGS cell, delivers new record power conversion efficiencies of 28.7% and 27.0%, respectively.

Small Robots Swimmers Heal Themselves when Damaged
Living tissue can heal itself from many injuries, but giving similar abilities to artificial systems, such as robots, has been extremely challenging. Now, researchers have developed small, swimming robots that can magnetically heal themselves on-the-fly after breaking into two or three pieces. The strategy could someday be used to make hardier devices for environmental or industrial clean up, the researchers say.

Pressure Sensors Ensure a Proper Helmet Fit to Protect the Brain
Many athletes, from football players to equestrians, rely on helmets to protect their heads from impacts or falls. However, a loose or improperly fitted helmet could leave them vulnerable to traumatic brain injuries. Now, researchers have developed a highly sensitive pressure sensor cap that, when worn under a helmet, could help reveal whether the headgear is a perfect fit.

New Copolymer Binder to Extend Life of Lithium Ion Batteries
The degradation of Li-ion batteries is a serious issue that greatly limits the useful life of portable electronic devices, indirectly causing huge amounts of pollution and economic losses. In addition to this, the fact that Li-ion batteries are not very durable is a massive roadblock for the market of electric vehicles and renewable energy harvesting.

Edible Holograms Could Someday Decorate Foods
Holograms are everywhere, from driver's licenses to credit cards to product packaging. And now, edible holograms could someday enhance foods. Researchers have developed a laser-based method to print nanostructured holograms on dried corn syrup films. The edible holograms could also be used to ensure food safety, label a product or indicate sugar content, the researchers say.

3D Printed Smart Gel Changes Shape When Exposed to Light
Inspired by the color-changing skin of cuttlefish, octopuses and squids, engineers have created a 3D printed smart gel that changes shape when exposed to light, becomes "artificial muscle" and may lead to new military camouflage, soft robotics and flexible displays.
