Artificial bees from a pressure cooker?

What if we could create artificial bees that helped us with food production? Ola Gjønnes Grendal cooks up the materials needed to do just this.

Device harvests energy from low-frequency vibrations

A wearable energy-harvesting device could generate energy from the swing of an arm while walking or jogging, according to a team of researchers from Penn State's Materials Research Institute and the University of Utah. The ...

Electric textile lights a lamp when stretched

Researchers at Chalmers University of Technology have developed a fabric that converts kinetic energy into electric power. The greater the load applied to the textile and the wetter it becomes, the more electricity it generates. ...

Piezomagnetic material changes magnetic properties when stretched

Piezoelectric materials, which generate an electric current when compressed or stretched, are familiar and widely used: think of lighters that spark when you press a switch, but also microphones, sensors, motors and all kinds ...

Acoustic device makes piezoelectrics sing to a different tune

In today's "internet of things," devices connect primarily over short ranges at high speeds, an environment in which surface acoustic wave (SAW) devices have shown promise for years, resulting in the shrinking size of your ...

Small scale energy harvesters show large scale impact

The production of nano-scale devices has drastically increased with the rise in technological applications, yet a major drawback to the functionality of nano-sized systems is the need for an equally small energy resource.
