Abstract: A light-emitting device preparation method includes: preparing one or more functional layers on a first electrode; preparing a second electrode on the one or more functional layers; wherein, at least one of the one or more functional layers is obtained by subjecting a solution of the corresponding functional layer material to a first thermal annealing treatment and then a second thermal annealing treatment.

Abstract: A thin film processing method includes: providing an electron transport film layer using a metal oxide as an electron transport material; and annealing the electron transport film layer by means of pulsed light in a protective gas environment having an oxygen content of 25-40 ppm.

Abstract: Systems and methods for a microfluidic biosensor patch and health monitoring system may include an iontophoresis module, a multi-inlet microfluidic sweat collection and sampling module, and a molecularly imprinted polymer (MIP) organic compound sensor module. An iontophoresis module may provide for stimulation of a biofluid sample. A biofluid may be a sweat sample. Stimulation may be achieved via electrostimulation and/or application of a stimulating agent. A microfluidic sweat collection and sample module may include several adhesive layers with carefully designed inlets, channels, a reservoir, and an outlet for the efficient collection and sampling of biofluid. A MIP sensor module may quickly and accurately identify concentrations of key metabolites present in a biofluid sample which may indicate certain health conditions.
