Multifunctional inkjet printed sensors for MMOD impact detection

Abstract: The sensitivity of the electronic properties of carbon nanotubes to gases, chemicals, temperature, and mechanical strain enables their use as fillers in nanocomposites for sensing applications. In this paper, the authors develop a low-cost and scalable process based on inkjet printing technology to fabricate printed flexible sensors used for strain and damage detection. A well-dispersed conductive water-based ink is fabricated with functionalized multiwall carbon nanotubes (MWCNT) and deposited onto paper and … Show more

“…In scientific research, commercially available, low-cost desktop office inkjet printers are frequently adapted for the deposition of functional materials. [89][90][91] Although this usually enables fast and cheap prototyping, high resolution printing can hardly be realized, and the lack of inkjet metrology tools makes it difficult to characterize and tune inkjet parameters. Specifically, the stability of the jetting process cannot be monitored and controlled, due to the absence of a drop-view camera.…”

“…100 Figure 7b shows a CNT layer printed on a Kapton ® film which was impacted with a high velocity projectile and the active signal generated from this impact. 100 The initial resistance spike followed by damping oscillations are attributed to instantaneous strain in the film followed by the shockwave after impact. Direct print additive manufacturing using CNT ink has also been used to construct an ultra-high frequency RFID-based passive wireless sensor for micrometeoroid and orbital debris impact detection.…”

“…Printable inks are based upon a careful selection of the ink components, including the functional material and (a combination of) solvents and stabilizers [ 13 ]. Metal nanoparticles [ 14 , 15 , 16 ], conductive polymers [ 17 , 18 ], and carbon nanomaterials [ 19 , 20 , 21 ] are the most used functional components in electrically conductive inks. When formulating inks, rheological properties must be carefully tailored to ensure proper jetting.…”
