Electrowetting-Based Actuation of Liquid Droplets for Micro Transportation Systems

Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2010
This paper describes the electrowetting-on-dielectric (EWOD) actuation of liquid droplets for transportation of micromechanical parts. As dimensions of mechanical parts decrease, surface tension and electrostatic force become dominant compared to gravity

Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying

Advanced Engineering Materials, EarlyView.
An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.

Fault Detection in High Redundancy Actuation Using an Interacting Multiple-Model Approach [PDF]

, 2009
The High Redundancy Actuation (HRA) project investigates the use of a relatively high number of small actuation elements, assembled in series and parallel in order to form a single actuator which has intrinsic fault tolerance.

Architecture‐Driven Sensor Stability in Weft‐Knitted Engineering Textiles

Advanced Engineering Materials, EarlyView.
Textile‐integrated sensor architectures are systematically compared to evaluate their electromechanical behavior under combined mechanical and environmental loading. Pocket‐based integration exhibits stable and reproducible signals, whereas tunnel‐based routing shows higher sensitivity accompanied by increased variability.
