Abstract:
1. A multi-layer, disposable, microsensor comprising: (a) an electrode layer comprising a first set of sensor electrodes, a second set of sensor electrodes and a temperature sensor; (b) a microfluidic layer with inlet/outlet ports consisting of: (b1) a one-piece microfluidic package with a first side on the one-piece microfluidic package having at least one set of interconnecting ports, the set having an inlet port and an outlet port, the set including one male port and one female port, (b2) an interior tube for the inlet port on the one-piece micro fluidic package and an interior tube for the outlet port, each interior tube having a diameter of less than approximately 1.00 mm. (b3) a second side on the one-piece microfluidic package, that is opposite to the first side, the second side having one of a microfluidic channel and a combination of a microfluidic channel and a fluid reservoir, the first side and the second side of the one-piece microfluidic package together solely providing a one-piece, integrally formed one-piece microfluidic package; and (c) an adhesive material to secure the electrode layer and the one-piece microfluidic layer in a stacked unitary arrangement for use in continuous monitoring of free chlorine in water.
