Human skin can sense subtle changes of both normal and shear forces as well as perceive stimulus with finer resolution than the average spacing between mechanoreceptors. By contrast, existing tactile sensors for robotic applications are inferior, lacking both accurate force decoupling and proper spatial resolution. This project aims at developing skin-alike soft tactile sensors based on principles of magnetic fields.
Low-grade heat, which is abundantly available in the environment and even in human body, is always wasted without use. Direct Thermal Charging Cell (DTCC) is invented for efficient heat-to-electricity conversion yielding a conversion efficiency over 5%, which surpasses all existing thermo-electrochemical and thermo-electric systems in low-grade heat regime.
The fluidic processor resembles a “magic” optical hand that can navigate, fuse, pinch, and cleave fluids in lossfree manner. Fluid placed on the device beads up like a marble and readily rolls without residue. By illuminating laser on the platform, a wavy force field is generated, acting as an invisible hand to touch and manipulate fluid.
How is the emerging new SARS-CoV-Z transmitted? This has been one of the major challenges for effective intervention since the COVlD-19 pandemic emerged in late 2019.
Following our continuous environmental studies of infection since 2003 SARS epidemics, our team immediately explored our long-held hypothesis that short-range inhalation transmission might predominate the spread of most respiratory infection.
Clean water and clean air are vital for public health. This project focuses on developing high-efficiency and environmentally sustainable filters for removing harmful air/water pollutants. The team has developed novel architectures and functionalities for the filters to achieve high permeance, high removal efficiency, and excellent reusability.
