We are witnessing the advent of the 4th industrial revolution, and are heading towards a largely robotized world. A lot of analogue electro-mechanical devices for sensing, actuation, communication, and fabrication are necessary ingredients for such revolution. Piezoelectricity plays an important role in any electro-mechanical conversion, and is used for instance in ultrasonic imaging and mobile phone communication. The necessary drive for miniaturization will result in a strong demand for piezoelectric thin films, with improved, optimized properties.
