A 3D-printed piezoelectric metamaterial uses topology-driven charge transport to locate underwater sound sources from a single compact transducer, replacing bulky hydrophone arrays.

The human body continuously generates a rich spectrum of vibrations—often without us ever noticing. Everyday unconscious ...

Botanical sensors are turning greenery into living data networks while monitoring plant health and optimizing yields.

Every time we feel a gentle tap on the skin, specialized nerve cells convert that physical force into an electrical signal that the brain can interpret as touch. While scientists have long known that ...

Imagine a world where microcontrollers (MCUs) and development boards operate without batteries. Energy-harvesting technology now makes this a practical ...

Abstract: For vibration sensors in wind tunnels, long-term online operation is required. Regular removal for calibration is impractical. This paper presents an online piezoelectric selfcalibration ...
