New Fabric Could Help Keep you Cool in the Summer

Researchers have developed a material that cools the wearer without using any electricity. The fabric transfers heat, allows moisture to evaporate from the skin and repels water.

3D Printed Latex Rubber Breakthrough

Researchers have discovered a novel process to 3D print latex rubber, unlocking the ability to print a variety of elastic materials with complex geometric shapes.

Researchers Print, Tune Graphene Sensors to Monitor Food Freshness

Researchers dipped their new, printed sensors into tuna broth and watched the readings. It turned out the sensors - printed with high-resolution aerosol jet printers on a flexible polymer film and tuned to test for histamine, an allergen and indicator of spoiled fish and meat - can detect histamine down to 3.41 parts per million.

Making 4D Printing More Practical

Soft robots and biomedical implants that reconfigure themselves upon demand are closer to reality with a new way to print shapeshifting materials.

Brain Signal Measurement Using Printed Tattoo Electrodes

Researchers have developed ultra-light tattoo electrodes that are hardly noticeable on the skin and make long-term measurements of brain activity cheaper and easier.

Expandable Foam for 3D Printing Large Objects

It's a frustrating limitation of 3D printing: Printed objects must be smaller than the machine making them. Huge machines are impractical for printing large parts because they take up too much space and require excessive time to print. Now, a new material can be used to 3D print small objects that expand upon heating. The foam could find applications in architecture, aerospace and biomedicine.

New Textile Could Keep You Cool in the Heat, Warm in the Cold

Imagine a single garment that could adapt to changing weather conditions, keeping its wearer cool in the heat of midday but warm when an evening storm blows in. Now, researchers report a strong, comfortable fabric that heats and cools skin, with no energy input.

Graphene Forms Under Microscope's Eye

You don't need a big laser to make laser-induced graphene. Scientists are using a very small visible beam to burn the foamy form of carbon into microscopic patterns.

A Self-Healing Sweat Sensor

Wearable sensors that track heart rate or steps are popular fitness products. But in the future, working up a good sweat could provide useful information about a person's health. Now, researchers reporting have developed a headband that measures electrolyte levels in sweat. And unlike many previous sweat sensors, the device can heal itself when cut or scratched during exercise.

Next-gen solar cells mimic photosynthesis with biological material

Next-generation solar cells that mimic photosynthesis with biological material may give new meaning to the term "green technology."

Fuel cells developed using nanomaterials are cost effective, efficient

A fuel cell can be built from cheaper, more widely available metals using an atomic-level design that also gives the material long-term stability.

Organic solar cells will last 10 years in space

Over the past two decades, organic solar cells have garnered much attention thanks to their light weight, flexibility and unprecedented energy-to-weight ratios of 10 to 20 W/g, which make them a promising candidate for space applications, although their radiation stability is still poorly
