Abstract:
1. A method for the manufacture of a product sensor effective for use in product control, the product sensor having an antenna circuit and at least one measuring device having at least one electrical property affected by at least one condition, the method comprising: applying a conductor on a first continuous flexible web to provide at least part of antenna circuits and form a first module web with the at least part of the antenna circuits in spaced relation along the first web; applying measuring devices on a second flexible continuous web to provide a measuring device web and form a second module web with measuring devices in spaced relation along the second web; and bonding the first module web with the second module web to provide a product sensor web with product sensors in side by side relation, the at least part of the antenna circuits on the first web and the measuring devices on the second web, the bonded modules and configured to effect at least one of the following: (a) the first module and second bonded to each other to electrically couple the first and second module and form a resonance circuit common to both modules and (b) the second module arranged in the product sensor to electrically alter properties of an electric resonance circuit within the first module.
