Piezoelectric Resonator with Two Layers

Microelectromechanical systems (MEMS) filters have advantages in being able to reduce the size, weight, and power required when used as part of electronic systems such as radios; however, MEMS-type filters have limitations. For example, thickness MEMS-type filters (e.g., thickness-extensional mode...

A new method increases the service life of concrete structures by reducing the infiltration rates of deleterious ions. The key is a nano-sized additive that slows down penetration of...

Who

The Safe Impact Resistant Electrolyte (SAFIRE) fire-resistant battery can be used in consumer electronics such as cellphones, in drones and cars, and in soldiers’ packs.

Kit Containing Stem Cells and Cytokines for Use in Attenuating Immune Responses

Stem cells have two distinct characteristics that distinguish them from other cell types. First, they are unspecialized and can self-renew for long periods without significant changes in their general properties. Second, under certain physiologic or experimental...

The Create the Future Design Contest was launched in 2002 by Tech Briefs Media Group (publishers of Tech Briefs magazine) to help stimulate and reward engineering innovation. Since...

Most metals, with the notable exception of gold, tend to oxidize when exposed to air and water. This reaction — which produces rust on iron, tarnish on silver, and verdigris on copper or...

A Biologically Inspired Method of Improving Systems and Survivability Through Self-Sacrifice

In human beings, the self-destruction behavior of human body cells is considered as an intrinsic safety mechanism of the human body. It seems that the lifetime of a cell is programmed, and that cells know when to commit suicide. This self-destruction is...

Advanced Thermal Solutions, Norwood, MA, announced the tvLYT liquid crystal thermography system that provides a portable solution for temperature measurement of...

Eagles can store energy in their feet without having to continuously contract their muscles to then jump high or hold on to prey. New materials have been created that can store energy this way. The...

Many low-cost sensors (or cameras) may spatially or electronically under-sample an image. Similarly, cameras taking pictures from great distances, such as aerial photos, may not obtain detailed...

Heart disease is the leading cause of death for both men and women, according to the Centers for Disease Control and Prevention (CDC). In the U.S., one in every four deaths is a result of heart...

Robots that are adapted to respond to physical human-robot interaction (pHRI) traditionally treat such interactions as disturbances, and resume their original behaviors when the...

Synthesis and Development of Polyurethane Coatings Containing Fluorine Groups for Adhesive Applications

Accumulation of insect strikes on the leading edge of airplane wings is a more serious problem than one might realize. Depending on the magnitude, such accumulation changes the aerodynamic characteristics of the wing, causing a change from...

Colloids — insoluble particles or molecules anywhere from a billionth to a millionth of a meter across — are so small they can stay suspended indefinitely in a liquid or even in air. Robots about...
