piezoelectric cells

An international team of scientists led by Penn State may have solved the 30-year-old riddle of why certain ferroelectric crystals exhibit extremely strong piezoelectric responses

How can a humpback whale and a device that works on the same principle as the clicker that starts your gas grill help an unmanned aerial vehicle (UAV) fly longer and with more stability?

Researchers from Columbia Engineering and the Georgia Institute of Technology have reported the first experimental observation of piezoelectricity and the piezotronic effect in an atomically thin material, molybdenum disulfide (MoS₂), resulting in a unique electric generator and mechanosensation devices that are optically transparent, extremely light, and very bendable and stretchable.

Anxiety? No problem. An electric vest can rub away your stress-filled day. Three Cornell students have developed a garment – embedded with piezoelectric cells and tiny motors – that gently massages the back and shoulders, mimicking a human touch.
