What are Piezoelectric Transducers?
Piezoelectric transducers are devices that convert mechanical energy into electrical energy and vice versa through the piezoelectric effect. This phenomenon occurs in certain materials, such as quartz and specific ceramics, which generate an electrical charge in response to applied mechanical stress.
How Do Piezoelectric Transducers Apply to Catalysis?
In the realm of
catalysis, piezoelectric transducers can be used to monitor and enhance catalytic reactions. They serve multiple purposes, such as measuring pressure changes, detecting reaction rates, and even initiating reactions through controlled vibrations. Their ability to provide real-time data makes them invaluable in both research and industrial settings.
