“…PE and OLAE are emerging technologies fueled by research on a new class of materials that can be used in large-area and high-volume deposition or printing/patterning of electronic components and devices [9][10][11]. The use of additive electronic manufacturing strategies allows for rapid development of case studies, and scale-up of new devices, while economizing materials [12][13][14]. Some physical components such as sensors, actuators, antennas, displays, energy harvesters, and organic batteries can already be obtained through PE and OLAE, however many of them still present performance limitations [9].…”

The emergence of novel materials with flexible and stretchable characteristics, and the use of new processing technologies, have allowed for the development of new connected devices and applications. Using printed electronics, traditional electronic elements are being combined with flexible components and allowing for the development of new smart connected products. As a result, devices that are capable of sensing, actuating, and communicating remotely while being low-cost, lightweight, conformable, and easily customizable are already being developed. Combined with the expansion of the Internet of Things, artificial intelligence, and encryption algorithms, the overall attractiveness of these technologies has prompted new applications to appear in almost every sector. The exponential technological development is currently allowing for the “smartification” of cities, manufacturing, healthcare, agriculture, logistics, among others. In this review article, the steps towards this transition are approached, starting from the conceptualization of smart connected products and their main markets. The manufacturing technologies are then presented, with focus on printing-based ones, compatible with organic materials. Finally, each one of the printable components is presented and some applications are discussed.

“…To improve the sensitivity and compensate for the temperature drift, we fabricated double-layer sensor arrays with a lamination process [10,11]. The parametric investigation of the double-layer sensor array is documented in [12]. On the top of the IDEs, a conductive organic piezoresistive material of poly (3,4-ethylene dioxythiophene) polystyrene sulfonate or PEDOT: PSS was applied as the active tactile sensing agent [10,11].…”

This paper presents the NeXus, a precision robotic platform with additive manufacturing capabilities that can be used to prototype strain gauge-based tactile sensors – SkinCells - on flexible substrates. An Aerosol Inkjet printer was employed to print the strain gauge structures of the SkinCell sensor. The design of this sensor combines curvilinear geometries representing both a radial shape structure and an arc shape structure, which have opposite gauge responses when the force is applied to the center of the sensor. The fabrication process of the SkinCell sensor is predicated on a parametric kinematic calibration of the NeXus to identify features on the sensor substrate and align them to the printing and metrology tools. Several strain gauge SkinCell sensor samples were printed on pre-fabricated flexible substrates using the NeXus. Results indicate a calibration precision of approximately 36 microns with 100 microns line-width features. This precision is sufficient to ensure that all printed gauges are electrically connected to the prefabricated contacts. Furthermore, the printing errors accumulating during a continuous four-sensor array print also fall within the contact tolerance.
