Today, researchers from the University of California, Berkeley have unveiled a revolutionary new device: the High Performance Microcone Array (HPMA). This device is a flexible piezoelectric acoustic array that can be used to detect, modulate, and generate sound. By utilizing tiny microcone structures on a flexible substrate, the HPMA has the potential to revolutionize acoustic technology. This device could be used to create ultra-sensitive microphones capable of detecting even the faintest sounds, or to make powerful ultrasonic speakers for use in medical, automotive, and consumer applications. With its potential to revolutionize acoustic technology, the HPMA could have far-reaching implications for the way we interact with our environment.
