Abstract:
A method for characterizing a plurality of materials, comprising the steps of:a) providing 5 to 400 sensors on a first array, each of said sensors being adapted for receiving a test sample of a material and each of said sensors being adapted for measuring a same first material property as each other sensor; b) connecting said first array to an interconnection device associated with electronic test circuitry for electrical communication between said first array and said electronic test circuitry; c) depositing a different individual material test sample onto each of said sensors, d) routing an electrical input signal to each of said sensors having a material test sample thereon; e) measuring a resulting electrical output signal from each of said sensors having a material test sample thereon; f) correlating any difference between said electrical input signal and said electrical output signal with said same first material property being tested; g)removing said first array; h) repeating said steps (a)-(f), substituting a second array of 5 to 400 sensors for said first array, each of said sensors in said second array being adapted for receiving a test sample of a material and each of said sensors of said second array being adapted for measuring a same second material property as each other sensor by way of said interconnection device.
