Stanford scientists have developed a method and apparatus for simultaneously measuring mucus rheology and cilia activity on live airway cells without removing mucus or inhibiting cilia function.
Magnetic field measurements using currently available devices require complex switching circuitry to mitigate the offset and noise present in measurements.
This patented technology is a magnetically actuated photonic crystal sensor system. It utilizes a photonic crystal (PC) coupled to magnetic material which is then mounted on an optical fiber.
