Variable Impedance Actuators: Moving the Robots of Tomorrow [PDF]

, 2012
Most of today's robots have rigid structures and actuators requiring complex software control algorithms and sophisticated sensor systems in order to behave in a compliant and safe way adapted to contact with unknown environments and humans.

A Simple Method to Allow Parylene-C Coatings on Gold Substrates

Proceedings, 2017
Parylene-C, a biocompatible coating material, does not adhere well to metals. This is problematic especially for biomedical devices containing gold structures.

Investigations of the key mechanism of Carbon-Nanotube Actuators and their dependencies [PDF]

, 2010
Future adaptable applications require electro-mechanical actuators with a high weight-related en-ergy. Among modern multi-functional materials carbon nanotubes (CNTs) have some special char-acteristics which give them the potential to solve this demand ...

Novel Design of Additively Manufactured Micromixer in a Microchannel Comprising Mounting and Sealing Elements

Proceedings, 2018
An additively manufactured three-dimensional mixing element (3DME) integrated in a microchannel is presented. The 3DME increases the interfacial contact-surface by swapping the positions of the incoming streaming liquids.

Design and Evaluation of Capacitive Smart Transducer for a Forestry Crane Gripper

Sensors, 2023
Stable grasps are essential for robots handling objects. This is especially true for “robotized” large industrial machines as heavy and bulky objects that are unintentionally dropped by the machine can lead to substantial damages and pose a significant ...

Feasibility of a Dielectric Elastomer Augmented Aorta

Advanced Science, 2021
Although heart transplantation is a gold standard for severe heart failure, there is a need for alternative effective therapies. A dielectric‐elastomer aorta is used to augment the physiological role of the aorta in the human circulatory system.

Flow-Ratio Monitoring in a Microchannel by Liquid-Liquid Interface Interferometry

Proceedings, 2017
A new method to monitor the relative flow rates of two different liquids in a microchannel is presented. By using a simple out-of-plane interferometer setup, shifts in the position of the interface between the two liquids can be determined.

Observer‐Based Adaptive Event‐Triggered Tracking Control for Fuzzy TS Systems With Premise Mismatch

International Journal of Adaptive Control and Signal Processing, EarlyView.
This paper presents an adaptive logistic event‐triggered observer‐based tracking controller for Takagi‐Sugeno fuzzy systems under constrained inputs and network delays. Leveraging a hybrid LMI and Secretary Bird Optimization approach, this strategy significantly minimizes communication overhead and computational burden while ensuring optimal reference ...
