“…Design of printed strain gages in this paper is improved compared to the design presented in our previous research [15], by increasing the length of the end loop. Proposed length of strain gage end loop is five times longer than grid track width.…”

In this paper, resistive strain gages designed and fabricated in inkjet printing technology with three different silver nanoparticle inks are presented. Inks have different Ag content (15, 20 or 25 wt%) and solvents (water type or organic type). Strain gages were printed on a 50 ?m thick polyimide and 140 ?m thick PET-based substrate with different printer types (professional and desktop). All printed sensors have the same size (17 mm ? 5 mm). To determine the change of resistance due to bending of the steel beam, tensile tests were performed up to 1500 microstrains. Due to performed cycles of loading and unloading of the steel beam, gauge factor and stability of the response of the strain gages are measured. Resistance change was measured with Keithley SourceMeter 2410. For acquisition of measured data, in-house software tool was developed. Measured gauge factors of the sensors are in the range between 1.07 and 2.03 (depending on a used ink, substrate and printer). Results of this research indicate the strain gages with good GF can be produced even with low-cost equipment, such as desktop printer EPSON C88+ and PET-based substrate.

“…As mentioned earlier, the dielectric constants of the substrate and air tend to be different, so waves propagate in a nonuniform medium. When the antenna is bent, the increase in dielectric constant is related to the decrease in thickness [39]. In conclusion, it is concluded that the bending behavior of rectangular patch antennas is the result of a combination of the bending axis, electromagnetic properties, and mechanical properties of the antenna assembly.…”

The technical method of strain detection by radio frequency identification (RFID) technology has the characteristics of flexibility, low cost and high intelligence. The traditional planar-based rigid sensing antennas are basically made of rigid substrates, which have the disadvantages of poor surface fit and flexibility, so flexible electronics are gradually applied in the field of structural health monitoring (SHM) to solve the challenge of nonplanar deformation monitoring. In this paper, we propose a flexible reconfigurable strain-gauge RFID sensor with an encoding capability of 4 bits. The encoding structure is based on a coupled U-shaped resonator with strain resonance in the UHF RFID frequency band from 0-4 GHz. Reconfigurability is achieved by introducing a diode with modulated bandstop filtering in the resonator. The proposed antenna uses an FPCB board with total dimensions of 100 mm × 71.4 mm × 0.508 mm. It is subjected to thermal stability experiments, four-point bending strain and strain monitoring inside concrete, and the simulation and measurement results verify the feasibility of the design. This is important for realizing high-performance integrated strain monitoring in structural health monitoring using RFID technology.INDEX TERMS Radio frequency identification (RFID), flexible, strain sensor, reconfigurable antenna

In this work, we present for the first time a new fabrication process based on a 3D direct laser writing technique which allows the patterning of several layers in a single step by adjusting the power supplied by the laser in function with the optical properties of the materials. This approach was used for the fabrication of a piezoresistive MEMS (Micro Electro-Mechanical System) sensor made of flexible substrate whose three constituting layers were designed in the same step. The characterization of the resulting graphene strain gauge integrated in a Kapton microcantilever has shown a high sensibility since a gauge factor of 20 was obtained, proving the potential of the fabricated flexible piezoresistive MEMS to be used as transducer for the development of low-cost sensing platforms.
