Patterning temporally dynamic 4D hydrogel and nanocomposite material gradients: predictive cellular and actuator responses
… factors. The first is that of the soft aquatic actuator (SAA) scaffold. In these, the natural hydrogel alginate (Alg) is integrated with starch-based viscosifying agents as well as the inorganic nanoclay, Laponite XLG (LAP) to prepare a family of hydrogel nanocomposites that are robustly curable …

Control de las fuerzas de fresado mediante actuadores piezoeléctricos
… of a fast feed system driven by a piezoelectric actuator to the conventional feed drive of the CNC machine tool. Previously, a mechanistic procedure was developed to calculate cutting forces in milling allowing tool runout. This procedure was used to build up a model of the dynamic behaviour of …

Crosslinked Hyaluronic Acid Hydrogel Networks Designed as Mechanical Actuators
… collection of polymers, known as polymeric actuators, have been devised with the ability to convert an external stimulus to a change in shape, size or permeability. The current options within polymeric biomaterials with multi-functionality include matrices that are biocompatible, …

Bi-Modal Excitation of a Supersonic Rectangular Jet
… sensing to excite jet flows. In this work, 4 actuators are placed along the span of the upper and lower nozzle surfaces for a total of 8 actuators. Upstream, each actuator has its own sensor that read the instantaneous pressure disturbance. Each actuator then responds with the opposite of that …

Design and control of high-speed and large-range atomic force microscope
… of a parameter estimation methodology for piezo actuator hysteresis modeling and compensation. Atomic force microscopes can provide nano-scale resolution images of sample surface topography in air, vacuum or in liquid. This instrument operates by scanning a micro-mechanical probe on a sample. A …

Microscale actuators from carbon nanotube and hydrogel composites
This thesis develops and tests a novel microactuator system using carbon nanotubes (CNT) and poly(N-isopropylacrylamide) (PNIPAM) hydrogel, which have been combined to make a microactuator system with a wide range of possible designs without needing to modify the fabrication approach. These …
