Over the past decade, many researchers have been working on small, portable diagnostic devices based on chemical reactions that occur on paper strips. Many of these tests make use of...

Wearable devices have been limited to sensing signals either on the surface of the skin or right beneath it. A new wearable ultrasound patch non-invasively monitors blood pressure in arteries...

Microwave signals are ubiquitous in wireless communications but interact too weakly with photons. A technique was developed to fabricate high-performance optical microstructures using lithium niobate, a material...

Directly converting electrical power to heat is easy; however, converting heat into electrical power is not as easy. To address this issue, a tiny silicon-based device was developed that can...

The connection of plastics and metals poses a challenge due to the different physical properties of the two materials. All conventional joining options, such as bonds using adhesives or rivets,...

Increase in bioethanol production throughout the US has led to an increase in the process coproduct — distiller’s grains with solubles (DGS). DGS can be used to feed...

Metal-air batteries are one of the lightest and most compact types of batteries but when not in use, they degrade quickly, as corrosion eats away at their metal electrodes. While...

Microphones and stethoscopes are regularly used by physicians to detect sounds when monitoring physiological conditions. These monitors are...

Researchers have developed a fundamentally new type of rotary electrical contact that addresses the two limitations of conventional brush/slip ring technology: 1) short operating lifetime due to sliding-contact...

In contrast with conventional light-emitting diodes (LEDs) that emit billions of photons simultaneously to form a steady stream of light, a single photon emitter (SPE) generates...

An ingestible pill was developed that, upon reaching the stomach, quickly swells to the size of a soft, squishy ping-pong ball big enough to stay in the stomach for an...

Used since 2013, electroceutical bandages — which use electrical impulses to treat medical issues — kill bacteria around a wound, allowing wounds to heal faster. In addition, if infection is...

Researchers at NASA’s Johnson Space Center improved their Flash Thermography capabilities by incorporating transient and lock-in thermography. By...

Silicon is a naturally occurring material commonly used as a semiconductor in electronic devices; however, researchers have exhausted the potential of devices with semiconductors made...

Advanced driver-assistance systems and autonomous drive technologies increase the complexity of automotive integrated circuits (ICs), making it harder to ensure that...

Researchers have integrated two technologies widely used in applications such as optical communications, bio-imaging, and Light Detection and Ranging (LiDAR) systems to create a new infrared light-focusing...

Lithium-ion batteries commonly used in consumer electronics are notorious for bursting into flame when damaged or improperly packaged. Inspired by the unusual behavior of some liquids...

Researchers have created stretchable, rubbery semiconductors including rubbery integrated electronics, logic circuits, and arrayed sensory skins fully based on rubber materials. The semiconductors have...

Researchers devised a method in which running a light emitting diode (LED) with electrodes reversed was able to cool another device nanometers away. They harnessed the chemical potential...
