Soft Packaging of Flexible Piezoelectric Actuators for Applications in Wearable Haptic Devices

This paper reports on the development of haptic systems based on ultra-thin PZT/Si actuators integrated into flexible, soft packaging with screen-printed stretchable wires. The hybrid incorporation of silicon-based components, along with soft electronics, supports the creation of large-area, shape-conformable devices for wearable electronics, aiming to provide targeted haptic stimulation.
