Techs of the Week

A method to detect image position errors includes forming a first pattern with a symbol embedded therein and a second pattern which, when positioned on the first pattern, exposes the symbol if the misalignment between the first and second patterns exceeds a position error tolerance. The symbol is perceivable with the unaided...

Techs of the Week

A cantilevered microbeam temperature sensor is free from the residual or induced stress characteristic of standard bridge-type strain gauges. The microbeam is supported at one end, and the other is free to oscillate relative to the substrate and is isolated from changes in strain caused from flexure of a diaphragm. The beam's...

Sensitive Prosthetic Arms

Advances in limb prostheses have not obscured the fact that these devices still lack a sense of touch. Now, scientists from Northwestern University in Chicago have shown that transplanting the nerves from an amputated hand to the chest allows patients to feel hand sensation there. The findings could pave the way toward...
