Abstract: This disclosure describes a multiplexing, wireless, batteiyless multiplexing paper sensor. The sensor includes a polymeric, non-cellulosic substrate that includes a radio frequency (RF) wireless communication ultra-wide band (UWB) antenna and a sensing element disposed on the polymeric, non-cellulosic substrate with and without molecular imprinted structures to immobilize specific target chemical or biological objects. The sensor is powered when a signal is received by the RF wireless communication UWB antenna and then takes measurements of a medium being monitored by the sensor. Data corresponding to the measurements is then transmitted from the sensor via the RF wireless communication UWB antenna.

Abstract: A digital microfluidic platform utilizes dual active matrix circuitry to actuate and heat liquid droplets on a biochip. Liquid droplets are introduced into a droplet handling area of the biochip where they can be actuated by electrodes residing in pixels of an actuating active matrix array according to the electrowetting on dielectric phenomenon and heated by heating elements residing in pixels of a heating active matrix array. Pixels of the actuating active matrix array and the heating active matrix array are independently addressable such that droplets in the droplet handling area can be selectively heated and actuated according to their location. The actuating active matrix array and heating active matrix array can be formed on the same or different substrates with the droplet handling area disposed above or between the substrates.
