Engineers create ultra-sensitive artificial skin

(Phys.org) -- Engineers from South Korea and the United States working together have developed a new type of artificial skin that is less complex, cheaper to make and more sensitive than other electronic sensors designed ...

Great frigatebirds wearing backpacks map the atmosphere

Scientists often field check their findings, heading outside to see if computer models match with what is happening in the real world. But doing so is challenging when the field is two and a half miles up. Enter a new field ...

Restoring touch in nerves damaged by injury

Tel Aviv University's new and groundbreaking technology inspires hope among people who have lost their sense of touch in the nerves of a limb following amputation or injury. The technology involves a tiny sensor that is implanted ...

Two-phase material with surprising properties

Microstructure and macroscopic electro-mechanical properties are closely coupled in so-called ferroelectric polymers. An explanation for the high temperature dependence of this coupling has now been found at TU Wien.

Listening to the whispers of individual cells

For the cells in our bodies to function as a unit, they must communicate with one another constantly. They secrete signalling molecules—ions, proteins and nucleic acids—that are picked up by adjacent cells, which in turn ...
