Plasmonic Force Propulsion for Small Spacecraft [PDF]

50th AIAA/ASME/SAE/ASEE Joint Propulsion Conference, 2014
Plasmonic force propulsion uses solar light focused on deep-subwavelength nanostructures to excite strong optical forces that accelerate and expel nanoparticle propellant. The concept was assessed within the context of precision pointing and position control for nano/pico-satellites.

Estimating propulsive forces—sink or swim?

Journal of Biomechanics, 2005
The purpose of this study was to investigate the validity of hydrodynamic force estimation in swimming as calculated by the quasi-static approach. To achieve this a full-scale mechanical arm was developed, built and tested. The mechanical arm, covered with a prosthetic shell and driven at the shoulder was used to simulate a single plane underwater ...

Propulsive forces in keratocyte migration

Proceedings of the First Joint BMES/EMBS Conference. 1999 IEEE Engineering in Medicine and Biology 21st Annual Conference and the 1999 Annual Fall Meeting of the Biomedical Engineering Society (Cat. No.99CH37015), 2003
To move forward, migrating cells pull rearward against extracellular matrix and exert traction forces. To elucidate the mechanism of traction force generation in keratocytes, the authors have measured the forces generated against ECM contacts on both the ventral and the dorsal surfaces of the lamella.
