For the various nano-fluidic based biomedical applications, the study of the drag of fluid flow is of interest. Among which, the study of boundary slip is one of the most important and popular issues. Hydrophobic surfaces, which are believed to have a slip length, play an important role in the fluidic applications. There are various methods to measure slip length on hydrophobic surface. This paper...
This paper presents a Nano-opto-mechanical actuator, which is driven by optical radiation force. The actuator consists of two waveguides, two identical ring resonators, and an actuator with Bragg reflector. Light is injected into the waveguides and coupled to the Bragg reflector via the ring resonator. The actuator is displaced by the optical force. The achieved maximum displacement of the actuator...
This paper presents a pressure sensor array based on optical force using Nano-opto-mechanical Systems (NOMS). It consists of a deformable diaphragm and a waveguide array. When pressure is applied on the diaphragm, the gap between the diaphragm and the waveguide is reduced. The induced optical force deforms the waveguide and change the optical loss. In the experiment, it measures up to 32 dB optical...
Osteoarthritis is a degenerative joint disease, which causes the degradation of articular cartilage and subchondral bone. The disease may result in mechanical abnormalities of the joints, including weight bearing joints such as the knees and hips. In this work, we analyze gait biomechanical data using neural network models to predict the level of joint deterioration and the level of pain in participants...
