| Abstract Scope |
Piezoelectric materials, particularly those based on Lead Zirconate Titanate (PZT), are gaining attention in haptic feedback technologies. PZT exhibits high piezoelectric coefficients and operates in broad frequency range, making it ideal for creating tactile responses in various devices. In this study, modified PZT was screenprinted onto high-temperature resistant glass with silver (Ag) as the sandwiching electrodes. CuO-modification of the PZT allowed it to be sufficiently sintered at a low temperature of 900°C and demonstrated excellent piezoelectric properties, achieving a high d33 value of 250-270 pC/N and d31 value of -40-50 pC/N. The piezoelectric haptic actuator made of this material system used standing lamb waves in a vibrating plate to produce a considerable haptic effect under sinusoidal excitation at 30 kHz. Despite a low unipolar voltage of 10 VPeak-to-Peak, it still produced a displacement of 1 µm. These results demonstrate the feasibility of CuO-modified PZT ceramics for piezoelectric haptic actuator applications. |
