What are Piezoelectric Transducers? Transducers are the “opposite” of actuators: they convert mechanical energy into electric energy, which can be read or transformed with an actuator. Their applications vary greatly. Microphones and guitar pickups convert sounds or vibrations into electrical energy; keyboards sometimes use piezoelectric transducers to detect keystrokes; the list goes on. The most [...]
What are Piezoelectric Sensors? Piezoelectric sensors are transducers that convert environmental conditions into readable and usable electrical signals. There are two types: active and passive. The former sends ultrasonic signals and waits for a response, after which it releases an electrical signal. Information regarding distance and depth can be obtained when analyzing the delay. The [...]
Interesting Information on a New Class of Piezoelectric Actuators and Assemblies from Piezo Direct Author – Hunter Liu – Contributing Editor, Piezo Direct Many companies who are thinking about integrating piezoelectric components into future products often ask many questions regarding how piezoelectric actuators function in a wide array of products. Here are some interesting information [...]
The possibilities are endless for the future of piezo technology. Just last month, NASA announced a collaboration with Georgia Tech Research Institute to build a 40,000 square foot outdoor footpath using piezoelectricity. This project is to show the public how this new and innovative technology could lead us to having self-powered cities. This will be [...]
