Claim 0:
1. A sensing system for wireless and passive monitoring of strain during a manufacturing process that depends on force to apply the energy into the manufacturing process, the sensing system comprising:
at least one surface acoustic wave, SAW, sensor for detecting strain, the at least one SAW sensor being positioned in a force path located on or in the structure of one or more objects under test; and
at least one transceiving antenna arrangement being connectable to the at least one SAW sensor,
at least one interrogation antenna for providing an interrogation signal, wherein the at least one transceiving antenna arrangement is arranged for wireless communication with the at least one interrogation antenna,
wherein the at least one SAW sensor and the at least one transceiving antenna arrangement are arranged to receive energy from the interrogation signal and output a strain response signal detected by the at least one SAW sensor in response to the interrogation signal, and
wherein the at least one interrogation antenna is positioned to transmit/receive signals only within a specifically designated zone including a manufacturing process zone and specifically excluding any zone which contains tools not in use.
