Stretchy solar cells a step closer

Organic solar cells that can be painted or printed on surfaces are increasingly efficient, and now show promise for incorporation into applications like clothing that also require them to be flexible.
13 Nov

Fabric alternative to batteries

A major factor holding back development of wearable biosensors for health monitoring is the lack of a lightweight, long-lasting power supply. Now scientists report that they have developed a method for making a charge-storing system that is easily integrated into clothing for "embroidering a charge-storing pattern onto any garment."

Nanowires heat wearable heater

Researchers have made a wearable heater by modifying woven Kevlar® fabric with nanowires that conduct and retain heat.

Growing functioning human neural networks in 3D from stem cells

A team of researchers has developed three-dimensional human tissue culture models for the central nervous system that mimic structural and functional features of the brain and demonstrate neural activity sustained over a period of many months.

Taking steps toward a wearable artificial kidney

Scientists report a new urea sorbent that could accelerate progress toward the development of a lightweight, wearable artificial kidney with the potential to make dialysis more convenient, comfortable and effective.

3D-printed lithium-ion batteries

Electric vehicles and most electronic devices, such as cell phones and laptop computers, are powered by lithium-ion batteries. Until now, manufacturers have had to design their devices around the size and shape of commercially available batteries. But researchers have developed a new method to 3D print lithium-ion batteries in virtually any shape.

Color-changing contact lens to monitor disease

For all the good they do, eye drops and ointments have one major drawback: It's hard to tell how much of the medication is actually getting to the eye. Now scientists report that they have developed a contact lens that changes color as drugs are released. This visual indicator could help eye doctors and patients readily determine whether these medications are where they should be.

Simple stickers may save lives of heart patients, athletes

Heart surgery can be traumatic for patients. Having to continuously monitor your status without a doctor when you are back home can be even scarier. Imagine being able to do that with a simple sticker applied to your body.

Portable cancer test uses smartphone, new gold biosensor

A research team is creating a new cancer-spotting tool that health care providers could eventually use in areas that lack hospitals, clinics and other treatment centers. The tool is based upon a unique gold biosensor the research team created. When paired with a computer or smartphone and other inexpensive tools, the system is capable of spotting cancer biomarkers from a blood sample.

A wearable device for regrowing hair

Researchers have developed a flexible, wearable photostimulator that speeds up hair growth in mice. They report their results in ACS Nano.
17 Sep

A new dimension for batteries

Engineers have created a thin battery, made of a few million carefully constructed "microbatteries" in a square inch. Each microbattery is shaped like a very tall, round room, providing much surface area - like wall space - on which nano-thin battery layers are assembled.
10 Sep

A pill for delivering biomedical micromotors

Using tiny micromotors to diagnose and treat disease in the human body could soon be a reality. But keeping these devices intact as they travel through the body remains a hurdle.
5 Sep

Wearable to monitor lithium levels

People living with bipolar disorder and depression will soon be able to use a unique wearable sensor to safely monitor their lithium drug levels.
3 Sep

A new generation of artificial retinas

Scientists report they have successfully developed and tested the world's first ultrathin artificial retina that could vastly improve on existing implantable visualization technology for the blind.

Lithium-ion batteries can't catch fire because they harden on impact

Lithium-ion batteries commonly used in consumer electronics are notorious for bursting into flame when damaged or improperly packaged. Inspired by the weird behavior of some liquids that solidify on impact, researchers have developed a practical and inexpensive way to help prevent these fires.
27 Aug

Water bottles and other recycled 3D printing materials

Soldiers on the battlefield or at remote bases often have to wait weeks for vital replacement parts. Now scientists report they have found a way to fabricate many of these parts within hours under combat conditions using water bottles, cardboard and other recyclable materials.
22 Aug

Novel sensors could enable smarter textiles

A team of engineers is developing next-generation smart textiles by creating flexible carbon nanotube composite coatings on a wide range of fibers, including cotton, nylon and wool.
22 Aug

A paper battery powered by bacteria

In remote areas of the world or in regions with limited resources, everyday items like electrical outlets and batteries are luxuries. Health care workers in these areas often lack electricity to power diagnostic devices, and commercial batteries may be unavailable or too expensive. New power sources are needed that are low-cost and portable.

Massachusetts Institute of Technology (MIT)

MIT has many relevant projects including biomimetic batteries and ones created using viruses, printed electronic circuits, printed energy harvesting and so on.

Paving the way to highly stretchable and transparent electronics

Scientists have proposed a novel method for the fabrication of highly transparent, electrically conductive, stretchable tough hydrogels modified by single-walled carbon nanotubes.
