Abstract:Although structural health monitoring (SHM) technologies using sensors have dramatically been developed recently, their capability should be evaluated from the perspective of the maintenance industry. As a first step toward utilizing sensors, the objective of the paper is to investigate the possibility of using sensors for inspecting the entire fuselage during C-check. First, we reviewed various sensors for their detection range, detectable damage size, and installed weight, which revealed that the piezoelectric wafer active sensor (PWAS) is the most promising sensor for aircraft SHM. Second, we performed a case study of inspecting the fuselage of Boeing-737NG using PWAS. To maintain the same detecting capability of manual inspection in C-check, we estimated the total number of sensors required. It turned out that utilizing sensors can reduce the maintenance downtime and thus, maintenance cost. However, even with a very conservative estimate, the lifetime cost was significantly increased due to the weight of sensor systems. The cost due to the weight increase was an order of magnitude higher than the cost saved by using SHM. We found that a large number of sensors were required to detect damage at unknown locations, which was the main cause of the weight increase. We concluded that to make SHM cost-effective, it would be necessary either to improve the current sensor technologies so that a less number of sensors are used or to modify the aircraft design concept for SHM.

“…PEDOT:PSS can be processed from a water emulsion, at low temperature, on large area, and with low-cost deposition techniques like die coating [10] drop casting [26], [28], spin coating [24], [31], aerosol printing [39], screen printing [30], and inkjet printing [13], [40]. In particular, inkjet printing is a very appealing fabrication method because it uses a small amount of material that is directly patterned with various form factors without the need for solvents and masks.…”

Inkjet printing is a viable method for rapid and low-cost manufacturing of flexible sensors. In this paper, we study a technique for inkjet printing of poly(3,4-ethylenedioxythiophene): poly(styrene sulfonate) (PEDOT: PSS) strips. A low-cost inkjet desktop printer is used for the fabrication of PEDOT: PSS resistive strips on polyimide substrates. Accounting for several geometries of printed PEDOT: PSS strips, we assess the variability of the fabrication process. Owing to the printing process, we can easily choose the width, length, and thickness. We found that printed strips on polyimide foils show a conductivity equal to 115 S/cm, which linearly increases with the strip thickness. The maximum variability is lower than 13%. The frequency analysis shows a purely resistive impedance in the frequency range investigated (100 Hz-100 kHz). Moreover, the strips folded up to 1000 times shows a resistance variation lower than 6%. The study demonstrates that inkjet printing is a viable method for the simple, fast, reliable, and low-cost fabrication of PEDOT:PSS-based sensors on plastic substrates and circuit interconnections

“…Piezoelectric and resistive sensors, photonic, temperature, and capacitive sensors and actuator combinations are also viable candidates for printing. For example, Shemelya et al developed capacitive copper wire mesh sensors using wire embedded with a fused deposition modeler, Aliane et al developed temperature sensors, and Thompson and Yoon printed strain sensors using an aerosol printing technique [2,33,34]. There are many advantages to printing these types of mechanical sensors as they typically permit flexibility in configuration and application seen in gravure-printed humidity sensors by Reddy et al [35].…”

“…Aside from the uses in prototyping, printed electronics allows for unparalleled customization and the development of process-specific applications. For example, basic sensors such as strain gauges can be incorporated into structures as needed during the manufacturing process [2]. Devices for specialized applications, such as biomedical sensors for specific chemicals and piezoelectric actuators for energy harvesting can be produced more effectively by employing a printing process.…”

The last two decades have seen evolution of smart materials and structures technologies from theoretical concepts to physical realization in many engineering fields. These include smart sensors and actuators, active damping and vibration control, biomimetics, and structural health monitoring. Recently, additive manufacturing technologies such as 3D printing and printed electronics have received attention as methods to produce 3D objects or electronic components for prototyping or distributed manufacturing purposes. In this paper, the viability of manufacturing all-printed smart structures, with embedded sensors and actuators, will be investigated. To this end, the current 3D printing and printed electronics technologies will be reviewed first. Then, the plausibility of combining these two different additive manufacturing technologies to create all-printed smart structures will be discussed. Potential applications for this type of all-printed smart structures include most of the traditional smart structures where sensors and actuators are embedded or bonded to the structures to measure structural response and cause desired static and dynamic changes in the structure.
