Patent ID: 11383238

Abstract:
A microfluidic apparatus is provided. The microfluidic apparatus includes an electrochromic layer including a plurality of individually independently addressable regions; a microfluidic layer defining a microfluidic channel for allowing a microfluid to pass therethrough; and a plurality of photodetectors configured to detect light transmit through the microfluid. The electrochromic layer is configured to be switched between a first state in which the plurality of individually independently addressable regions of the electrochromic layer are substantially transmissive, and a second state in which at least a first one of the plurality of individually independently addressable regions of the electrochromic layer in a region corresponding to a position of the microfluid is substantially transmissive, at least a second one of the plurality of individually independently addressable regions of the electrochromic layer outside the region corresponding to the position of the microfluid is substantially non-transmissive.
