Claim 33:
34. 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,
wherein the at least one SAW sensor and the at least one transceiving antenna arrangement are arranged to receive energy from an interrogation signal and output a strain response signal detected by the at least one SAW sensor in response to the interrogation signal, and
a computing device for processing the detected strain response signal, the processing unit being connected to the at least one interrogation antenna, wherein the computing device is arranged to transmit the interrogation signal and transmission energy to the at least one transceiving antenna and to the at least one SAW sensor via the at least one interrogation antenna, and
wherein the computing device is arranged to receive the detected strain response signal via the at least one interrogation antenna,
wherein the computing device uses the detected strain response signal as a quantifiable metric that represents the strain experienced in the force path of the manufacturing process and which can be used as an input to a digital twin for the calculation of process forces during the manufacturing processes.
