Multi‐layer electrical interconnects are critical for the development of integrated soft wearable electronic systems, in which functional devices from different layers need to be connected together by vertical interconnects. In this work, electrohydrodynamic (EHD) printing technology is studied to achieve multi‐layer flexible and stretchable electronics by direct printing vertical interconnects as vertical interconnect accesses (VIAs) using a low‐melting‐point metal alloy. The EHD printed metallic vertical interconnection represents a promising way for the direct fabrication of multilayer integrated electronics with metallic conductivity and excellent flexibility and stretchability. By controlling the printing conditions, vertical interconnects that can bridge different heights can be fabricated. To achieve reliable VIA connections under bending and stretching conditions, an epoxy protective structure is printed around the VIA interconnects to form a core‐shell structure. A stable electrical response is achieved under hundreds of bending cycles and during stretching/releasing cycles in a large range of tensile strain (0–40%) for the printed conductors with VIA interconnects. A few multi‐layer devices, including a multiple layer heater, and a pressure‐based touch panel are fabricated to demonstrate the capability of the EHD printing for the direct fabrication of vertical metallic VIA interconnects for flexible and stretchable devices.

“…In fact, the discovery of carbon nanotubes [20] has opened the horizons for broad application in electrochemistry [21][22][23] due to their remarkable features such as high thermal conductivity, metallic or semi-metallic behavior, ultra-light weight, mechanical strength, large surface-to-volume ratio, and high electrical conductivity [24,25]; indicating the ability of these materials to facilitate a more effective electronic transfer. Consequently, CNT-based sensors had faster electron transfer kinetics, lower detection limit, and higher sensitivity compared with conventional sensors [26][27][28][29][30][31][32][33][34].…”

Two sensitive and selective potentiometric sensors based on zinc‐iron layered double hydroxides/multiwalled carbon nanotubes (Zn−Fe LDH/MWCNTs) (sensor I) and graphene/multiwalled carbon nanotubes (Gr/MWCNTs) (sensor II) nanocomposites were developed for benzydamine hydrochloride (Benz) determination. The investigated sensors displayed excellent Nernstian slopes 58.5±0.7 and 59.5±0.5 mV decade−1, detection limits 8.3×10−7 and 1.9×10−7 mol L−1, long lifetimes, adequate selectivity, high chemical, and thermal stability within pH range of 2.4–8.5 for sensors І and ІІ, respectively. The surface morphology of sensors was analyzed using a Transmission Electron Microscope (TEM). The analytical method was efficiently implemented for Benz determination in biological fluids and surface water samples.

“…Examples can be found across many research areas, from wearable devices for medical use [1][2][3][4] , to healthcare sensors that help improve lifestyle or habits such as exercise and sleep 5,6 . However, several studies have noted that the low conductivity of commercially available carbon black-based polylactic acids (CB-PLA) directly impacts the performance of the sensors [7][8][9][10] . It is possible to partially overcome this problem via additional filament doping or through chemical and electrochemical post-processing that can enhance the electron transfer kinetics of the final sensor surface [9][10][11] .…”

3D-printing has become a fundamental part of research in many areas of investigation since it provides rapid and personalized production of parts that meet very specific user needs. Biosensing is not an exception, and production of electrochemical sensors that can detect a variety of redox mediators and biologically relevant molecules has been widely reported. However, most 3Dprinted electrochemical sensors detailed in the literature rely on big, individual, single-material electrodes that require large sample volumes to perform effectively. Our work exploits multi-material fused filament fabrication 3D-printing to produce a compact electrochemical sensor. The device features a built-in well with a volume of approximately 100 μL where the sample is deposited and analyzed via cyclic voltammetry, differential pulse voltammetry, and chronoamperometry to assess sensor performance and sensitivity. The integrated 3D-printed platform successfully detects electrochemical activity for hexaammineruthenium (III) chloride and potassium ferricyanide (0.1 mM to 2 mM in 100 mM KCl), dopamine (50 μM to 1 mM in 1xPBS), and glucose via mediator-free and mediated amperometric glucose oxidase enzyme-based sensors (1 mM to 12 mM in 1xPBS), indicating good acceptance of biological modification. These results reveal the exciting potential of multi-material 3D-printing and how it can be used for the rapid development of efficient, small, integrated, personalized electrochemical biosensors.
