A lab developing environmentally friendly lead-free ferroelectric and piezoelectric ceramics.

AboutAbout the lab
Developing environmentally friendly lead-free ceramics.
The Nagata Lab studies ferroelectric and piezoelectric ceramics, which convert between electrical and mechanical energy.
Current ferroelectric and piezoelectric ceramics contain large amounts of lead.
The lab develops materials for environmentally friendly, lead-free ferroelectric ceramics.
It also works to extend them to a variety of functional electronic devices, such as sensors, actuators, resonators, and ultrasonic devices.
Key terms
- Piezoelectric ceramics
- A type of functional electronic ceramic; an element that converts between electrical and mechanical energy. Current ones contain large amounts of lead
- Lead-free
- Containing no lead in the material. Current ferroelectric and piezoelectric ceramics contain large amounts of lead
