A new type of ferroelectric polymer that is exceptionally good at converting electrical energy into mechanical strain holds promise as a high-performance motion controller or “actuator” with great potential for applications in medical devices, advanced robotics, and precision positioning systems, according to a team of international researchers led by Penn State.

Mechanical strain, how a material changes shape when force is applied, is an important property for an actuator, which is any material that will change or deform when an external force such as electrical energy is applied...

Nanomaterial feature could help electronic circuits adopt benefits of human memory. For all of the unparalleled, parallel-processing, still-indistinguishable-from-magic wizardry packed into the three pounds of the adult human brain, it obeys the same rule as the other living tissue it controls: Oxygen is a must.

So it was with a touch of irony that Evgeny Tsymbal offered his explanation for a technological wonder — movable, data-covered walls mere atoms wide — that may eventually help computers behave more like a brain.

“There was unambiguous evidence...
