Mechanical computer relies on kirigami cubes, not electronics

North Carolina State University researchers have developed a kirigami-inspired mechanical computer that uses a complex structure of rigid, interconnected polymer cubes to store, retrieve and erase data without relying on ...

Brain-inspired computing may boil down to information transfer

The biological brain, especially the human brain, is a desirable computing system that consumes little energy and runs at high efficiency. To build a computing system just as good, many neuromorphic scientists focus on designing ...

Building a supercomputer on wheels

Modern cars are packed full of electronics. Managing all the computers and assistance systems is a complex task, and the cable harnesses increase the weight of the car. In the joint research project CeCaS, Fraunhofer researchers ...


A 20 kW laser system for producing high-purity crystals

High-purity semiconductor crystals are required for power electronics in electric cars or in photovoltaics. When such crystals reach a diameter of 2 inches, they become relevant for industrial applications.

Why is it so hard to make batteries smaller and lighter?

Flat coin cell batteries (the kind used in watches) have been around for decades. But the combination of solid and liquid components makes it very hard to see how the components fail inside these batteries.
