Comprehensive Piezoelectric Material Performance and Application Technology
■ Technology
Using an innovative niobate–perovskite synthesis route, the sintering temperature is reduced to 1000~1100 ℃ per endnproduct requirements, delivering substantial, acrossnthenboard enhancements in piezoelectric parameters. The lowntemperature confiring formulation is applicable to stacked multilayer piezoelectric ceramics as well as singlenlayer, highnpower, MHznclass ultrasonic piezoelectric modules. ITRI’s MCL piezoelectric formulations meet leading international specifications and have been validated through collaborations with domestic and global electronicnceramics manufacturers.
■ Features
Using ultrasonic transducers—the most prevalent piezoelectric application—as an example, the technology addresses insufficient vibration amplitude, bandwidth limitations, low electromechanical conversion efficiency, and thermal degradation.

Sensor Components and Module Application Technology
■ Flexible Pressure Sensor Components & Modules
• PressurenSensing Insoles
▶ Wearable wireless insoles integrate acquisition, transmission, and processing to stream realntime plantar pressure maps,
logging left/right pressure distribution, weight distribution, gait and cadence, and dynamic Center of Pressure(COP).
Algorithms with HMI enable instant gaitnparameter readout. Applications include medical care, rehabilitation, sports
training, and footwear selection.
• Gait Measurement
▶ Flexible Pressure Sensing: Using pressure data and algorithms to compute step count, walking speed, stride length, cadence,
and TUG; automated analysis for results presentation; longitudinal trends assess muscle activity; bigndata analytics map
metrics to specific indications.
• Smart Bed Sheet
▶ A thin pressurensensing sheet with>200 sensing nodes coupled with AI posture recognition identifies six postures—sitting
on left/right edge, sitting upright on bed, supine, left/right lateral—and the last leavenbed position. Provides automated
24/7 activity logging and quantitative analysis for lifestyle and activity assessment.
