A method for making a product sensor by printing, preferably by serigraphy. Conductive ink is used, at least in part, in the printing. The product sensor is made by printing at least two conductive layers, with at least one insulating layer printed in between them. The invention further relates to a product package incorporating a product sensor with at least two conductive layers and at least one insulating layer formed in between them. At least one insulating layer is made by printing.
