Modeling piezoelectric stack actuators for control of micromanipulation [PDF]
IEEE Control Systems, 1997 A nonlinear lumped-parameter model of a piezoelectric stack actuator has been developed to describe actuator behavior for purposes of control system analysis and design, and, in particular, for microrobotic applications requiring accurate position and/or force control.

Shaping Carbon Nitrides for Advanced Macrostructures
Advanced Materials Technologies, EarlyView.This review examines how carbon nitride can be shaped through a range of printing and interfacial assembly methods. By bringing together additive manufacturing and liquid–liquid structuring concepts, carbon nitride is moving beyond its traditional powder‐based photocatalyst form toward digitally designed robust macroscale architectures with high design

Improvement in Durability of Piezoelectric Stack Actuator.
Journal of the Ceramic Society of Japan, 1999 A study of durability test was piezoelectric stack actuator having various values of Qm, Tc, Ec and bending strength. The high bending strength but low Ec stack showed a decrease of displacement and appeared cracks which occurred at the edge of positive side of PZT pellet and grown to the center of diameter and negative side.

Multimodal Haptic Perception Through Synergistic Nanocomposite Sensor Arrays
Advanced Materials Technologies, EarlyView.Multi‐modal fingertip haptics are advanced through a bioinspired &vertical‐via' electronic skin architecture. A confined PDMS/MWCNT/NiNP nanocomposite, sitting at the percolation threshold, enables tactile, thermal, and magnetic sensing. A unique via‐density gradient and dedicated &Un‐Touch' reference nodes provide robust spatial resolution and signal ...
