The simplest piezo drive circuit consists of a transducer and a switching transistor (Figure 1). The voltage across the transducer cannot be greater than the supply voltage, which places an upper ...

Will piezoelectric-based speakers replace traditional speakers over the coming years in space-constrained devices? We have definitely seen the use of piezo transducers in e.g. high-end televisions … ...

Ever hear of a piezo-optomechanical circuit? We hadn’t either. Let’s break it down. Piezo implies some transducer that converts motion to and from energy. Opto implies light. Mechanical… ...

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 ...

When used with the DRV2901 piezo transducer driver as a companion amplifier, the chipset provides ULC functionality in a compact footprint with a PCB size measuring less than 25 × 15 mm.

It works by transmitting sound waves into an object using a piezoelectric transducer, then using the same transducer to pick up sound reflected from structures within the object. The resulting ...

Types and Versions of Piezo Transducers. Piezo elements can be crafted into several types of actuators, depending on what the needs are: disc transducers, bender actuators or piezo stacks.
