Cancer-detecting Bra
Dense breast tissue presents a higher risk of breast cancer developing than breast tissue with low density. This denser tissue is related to higher rates of false positive and false negative results from mammography or ultrasound, leading to unnecessary breast biopsy surgeries or failure to detect abnormal tissue. This project with Cyrcadia Health, Inc. developed an original device that has achieved FDA 510K clearance with 650 patients and the on-going final 173 BI-RADS 4/5 patient trail at JamesCare Comprehensive Breast Center in Ohio State University and The El Camino Hospital in Silicon Valley is positively tested and is being commercialized for product release in 2015.

Multiphysics Modeling of Smart Hydrogel in BioMEMS
So far the six multiphysics models have been developed theoretically for simulation of the fundamental mechanism and performance of the smart hydrogels responsive to the six kinds of external stimuli in environment solutions respectively. They include (1) solution pH, (2) externally applied electric field, (3) pH coupled with electric field, (4) temperature, (5) glucose/carbohydrates, and (6) salt concentration/ionic strength. All the six models are based on the laws of mass and momentum conservations, and include the effects of multiphases (the 3-D solid polymeric matrix network, interstitial fluid and ion species) simultaneously and chemo-electro-mechanical coupled multi-fields. Computational domains are defined as covering both the smart hydrogel and surrounding solution, in which the moving interfaces between the hydrogel and solution are modeled approximately and the boundary conditions are imposed on solution edges. The work has been extended to transient simulation of controlled drug release from micro-hydrogel particles.

Multiphysics Modeling of Moving Deformable Cells in Microscale Hydrodynamic and/or Electric Fields
A two-fluid model is developed for flow characteristics of cell suspending in a fluid, considering the interaction between cell and hydrodynamic field, identified by the membrane mechanical force, in which the cell membrane is treated as an incompressible and elastic shell with a uniform thickness and allowed to undergo the stretching and bending deformation; the interaction between the cell and electric field, identified by the dielectrophoresis (DEP) force due to the cell polarization through the Maxwell stress tensor (MST) approach; and the interaction between the two cells, identified by the intercellular interaction force behaving as a weak attractive force at far distance but a strong repulsive force at near distance through the Morse potential model.

A new bi-leaflet valve reconstruction for right ventricular outflow tract.
This is a joint project with KK Women’s and Children’s Hospital currently funded by NMRC starting March 2016 for 3 years. The objective is to design a bi-leaflet valve for small conduit for pediatric application. The novelty of this bi-leaflet valve design is that is will continue to serve its purpose as the conduit enlarges as the child grows. The purpose is to delay an imminent re-operation

Principal Investigator: Associate Professor Yeo Joon Hock

Mitral Valve reconstruction
