Low-cost multilaminate sensors

Abstract

Methods of monitoring environmental variables in general and chemical composition in particular, and sensors for such monitoring. These low-cost sensors comprised multiple layers in a laminated stack. Very high numbers of sensing layers (e.g., 500) may be incorporated into a single laminated sensor device. The sensors may signal changes in environmental state such as chemical composition due to changes in sensor properties such as resistivity, capacitance, inductance, permittivity, permeability, refractive index, chromaticity, transparency to light, reflection characteristics, resonance frequency, and/or magnetic characteristics.
