In one study, a z-structured piezoelectric transducer was developed to achieve a low-frequency, compact design by utilising a bender beam that couples longitudinal and bending vibrations—a ...

In this paper, we propose a novel piezoelectric micromachined ultrasonic transducer (PMUT) for airborne object detection, which provides high sensitivity compared to the conventional round-shaped PMUT ...

This paper proposes a piezoelectric-capacitive hybrid micromachined ultrasonic transducer (HMUT). The operation mode of HMUT integrates piezoelectric torque and electrostatic forces on the vibration ...

The global endocavity transducer market is estimated to be valued at USD 4,101.3 million in 2025 and is projected to reach USD 6,038.2 million by 2035, registering a compound annual growth rate (CAGR) ...

Companies across Europe are developing the next generation of sensors for medical applications, from Covid-19 testing to ...

Tired of loud TV ads? In 2012, Peter de Bruijn built the Mini-Mute — a clever circuit that let him mute his TV with a simple tap on the coffee table. Here's how it works.
