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.
