| 摘要 |
The invention relates to a method for manufacturing a product sensor ( 2 ), and a product sensor ( 2 ). In the manufacturing method, a circuitry pattern is formed in the product sensor ( 2 ) for achieving an antenna circuit (L, C 1 , C 2 ). In addition, the product sensor ( 2 ) is provided with at least one measuring means ( 13 ), whose at least one electrical property is affected by at least one condition. Product control is performed by measuring the at least one measuring means ( 13 ) formed in the product sensor ( 2 ), which means is affected by at least one condition, at least one electrical condition. In order to form a product sensor, at least a first ( 3 ) and a second module ( 5 ) are formed, the first of the modules ( 3 ) being provided with at least a part of said antenna circuit, and the second module ( 5 ) being provided with said at least one measuring means ( 13 ). Said at least two modules ( 3, 5 ) are connected to each other.
