Strain engineering and strain measurement by spring tethers on suspended epitaxial GaN-on-Si photonic crystal devices
Suspended epitaxial gallium nitride (GaN) on silicon (Si) photonic crystal devices suffer from large residual tensile strain, especially for long waveguides, because fine structures tend to crack due to large stress. By introducing spring-like tethers, des ...
Bristol20243D printed fiber-optic nanomechanical bioprobe
Sandor Kasas, Jiangtao Zhou, Yiping Wang, Yuguang Chen
Ultrasensitive nanomechanical instruments, e.g. atomic force microscopy (AFM), can be used to perform delicate biomechanical measurements and reveal the complex mechanical environment of biological processes. However, these instruments are limited because ...
IOP Publishing Ltd2023Learning Dynamics of Spring-Mass Models with Physics-Informed Graph Neural Networks
Olga Fink, Vinay Sharma, Manav Manav
We propose a physics-informed message-passing graph neural network (GNN) for learning the dynamics of springmass systems. The proposed method embeds the underlying physics directly into the message-passing scheme of the GNN. We compare the new scheme with ...
Research Publishing2023Resonant Transducers Consisting of Graphene Ribbons with Attached Proof Masses for NEMS Sensors
The unique mechanical and electrical properties of graphene make it an exciting material for nanoelectromechanical systems (NEMS). NEMS resonators with graphene springs facilitate studies of graphene's fundamental material characteristics and thus enable i ...
Washington2023Clip connector device and uses thereof
A removable clip connection device particularly adapted to bamboo structures is disclosed, as well as assemblies formed with the same and uses thereof. The clip connection features a base (100) located at a first end (10) of the device, said base having a ...
2022An elastic rod in frictional contact with a rigid cylinder
Pedro Miguel Nunes Pereira de Almeida Reis, Tomohiko Sano, Paul Grandgeorge
We investigate the load transmission along an elastic rod of finite cross-section in contact with a rigid cylinder, as system often referred to as the generalized capstan problem. In the presence of friction, the idealized classic capstan equation predicts ...
PERGAMON-ELSEVIER SCIENCE LTD2022An Inertial Uni-Axial Interferometer-Based Accelerometer for Harsh Environments
Mark Edward John Butcher, Gerard Aliana Cervera
For high-impact devices, subsequent vibrations have as much influence on the deterioration of the mechanical structure as the impact itself. To mitigate the consequences of both impacts and resulting vibrations, it is crucial to accurately understand the p ...
IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC2022Numerical simulations of retrofitting interventions on timber floors in unreinforced masonry
Katrin Beyer, Igor Tomic, Ivana Bozulic
Unreinforced masonry buildings with flexible timber floors are amongst the most vulnerable building typologies for seismic loading. Though flexible diaphragms play a role in the seismic behaviour of unreinforced masonry buildings, the impact of the connect ...
