Researchers develop world's thinnest electric generator

Researchers from Columbia Engineering and the Georgia Institute of Technology report today that they have made the first experimental observation of piezoelectricity and the piezotronic effect in an atomically thin material, ...

When roots crack and worms crunch

Roots can be "listened to" while growing – and worms when burrowing. Researchers from ETH Zurich and the French National Institute for Agricultural Research present a new method for soil analysis.

Study discovers amazing electrical properties in polymers

(PhysOrg.com) -- Crystals and ceramics pale when compared to a material researchers at Oak Ridge National Laboratory discovered that has 10 times their piezoelectric effect, making it suitable for perhaps hundreds of everyday ...

Pressure sensor array made with polyamino acid

Japanese researchers from the National Institute of Advanced Industrial Science and Technology (AIST), have developed an all-printed flexible pressure sensor in collaboration with Ajinomoto Co., Inc.

Lead-free piezoelectric materials of the future

Piezoelectric materials have fantastic properties: squeeze them and they generate an electrical field. And vice-versa, they contract or expand when jolted with an electrical pulse. With a name derived from the Greek word ...
