By combining TDK's core technologies such as ferrites, magnets, piezoelectric materials, semiconductor ceramics, and the circuit technologies, we develop an assortment of sensors and actuators. In the sensor field, we have put our multilayering technology nurtured in the chip condenser field to full use, and have made the smallest chip NTC in the industry and piezoelectric multilayer elements available to the market ahead of the world. We have in turn produced NTC thermistors, surface potential sensors, and toner concentration/residual volume sensors. In the actuator field, we offer simple design miniature plungers and nebulizer units. We help you save space otherwise taken by an assortment of small appliances.
