Abstract

Passive wireless patch antenna sensors have been developed in recent years to provide convenient and low-cost strain sensing for structural health monitoring (SHM). Current studies mainly focus on strain measurement in one direction, which is not sufficient for quantifying arbitrary strain field in many applications. This paper presents strain sensor rosettes made of two types of antenna sensors, folded patch antenna sensor and slotted patch antenna sensor, for measuring an arbitrary surface strain field. The transverse strain effect in both types of antenna sensors has been discussed. Mechanicselectromagnetics coupled simulation is conducted to validate the strain sensing performance of the strain rosettes made of antenna sensors. Numerical results show that both types of strain sensing rosettes can measure an arbitrary surface strain field with acceptable accuracy.
