Vascular Injury Shunt

Extremity vascular injury results in bleeding and lack of blood flow beyond the site of vessel disruption (ischemia). Priorities when this occurs include hemorrhage control, management of life-threatening injuries, and restoration of flow to the extremity. While definitive vessel repair is optimal, life-threatening injuries...

Design Software Identifies a Product's Performance Tradeoffs

Designing any product — from complex car parts to wrenches — is a balancing act with conflicting performance tradeoffs. Making something lightweight, for instance, may compromise its durability.

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...

Double-Fed Induction Linear Alternator

This technology was developed to address the limitations of traditional, single-fed linear alternators that require permanent magnets, adhesive bonding organics, and heavy iron laminations for flux control. They experience eddy-current losses and require electromagnetic interference protection. Furthermore,...

Wood-Based Technology Creates Electricity from Heat

Researchers have transformed a piece of wood into a flexible membrane that generates energy from the same type of electric current (ions) on which the human body runs. This energy is generated using charged channel walls and other unique properties of the wood’s natural nanostructures. With...

Battery Electrolyte Doubles Driving Range for Electric Vehicles

Conventional electrolytes used in lithium-ion batteries that power household electronics like computers and cellphones are not suitable for lithium-metal batteries. Lithium-metal batteries that replace a graphite electrode with a lithium electrode are the holy grail of energy...

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,...

Smart, Soft, Back Orthosis Uses Real-Time Motion Detection

Back pain is inevitable with constrained posture over a number of hours. Permanent damage such as premature spine wear is not uncommon in people who do not adopt proper ergonomic posture. The same applies to those who frequently lift heavy objects.

Algorithm Predicts How Electromagnetic Waves Interact with Materials at the Smallest Scales

Magnetic materials can attract or repel each other based on their polar orientation — positive and negative ends attract each other, while two positives or two negatives repel. When an electromagnetic signal like a radio wave passes through such...

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...

Improved Directed Flux Motor

Electromagnetic motors typically convert electrical energy into rotational mechanical energy and are employed across a wide array of applications. While motors represent relatively mature technology, practitioners continue to seek ways to enhance motor operation including a decrease in cost, drop in size/weight,...

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...
