An emergent direct‐write approach, aerosol‐jet printing (AJP), is gaining attention for the deployment of rapid and affordable microadditively manufactured energy‐efficient sensors and printed electronics. AJP enables a broad range of ink viscosities (0.001–1 Pa s) for printing diverse materials ranging from ceramics and metals to polymers and biological matter. Reproducible, high‐spatial‐resolution features (≈10 µm), and wide standoff distances (1–11 mm) between the nozzle and the substrate facilitate conformal printing of complex geometrical designs on nonplanar—e.g., stepped or curved—surfaces. This paper aims to provide a comprehensive overview of state‐of‐the‐art AJP‐based sensors (e.g., strain and temperature gauges, biosensors, photosensors, humidity and surface acoustic wave sensors, dielectric elastomer actuators, and motion, smoke, and hazardous gas detectors) and to discuss prospective applications. The drive toward cost‐effective devices that are smaller, lighter, and better‐performing remains a frontier challenge in the field of printed electronics. Consequently, as AJP becomes increasingly utilized in the high‐volume manufacturing of miniaturized active and passive sensors, it opens a pathway for facile large‐scale fabrication of devices for a wide range of consumer and industrial applications, including transportation, agriculture, infrastructure, aerospace, national defense, and healthcare.

“…HE recent advancements in technologies related to printed electronics brought significant innovation in the design and fabrication of electrochemical miniaturized sensors. By printing the electrodes and tracks on selected substrates (e.g., alumina, paper, plastic), it is thus possible to reduce the size of the macroscopic traditional electrochemical cell down to a few square millimeters, with advantages in terms of reduction of material waste, the possibility of integration in complex systems and analysis of low volume samples [1].…”

The recent advancements in technologies related to printed electronics brought significant innovation in the design and fabrication of electrochemical miniaturized sensors. One of the most exciting categories that can benefit from the transition from macro to micro enabled by novel printing techniques is ion-selective electrodes (ISEs). Miniaturized ISEs are also called All-Solid State ISEs (ASS-ISEs) since they rely on a solid contact transduction layer, enabling easier miniaturization and integration. This is particularly interesting for a wide variety of applications ranging from medical to industrial. In all these fields, printed ASS-ISEs have been proven to reach significant results in terms of metrological properties obtaining near-Nernstian sensitivities, limits of detection down to 10-10, best selectivity coefficients around 10-8, shorter response time lower than 5 s, stability reaching 6 months and optimal variabilities (with best repeatability lower than 1% and reproducibility lower than 2%). The use of innovative printing techniques could further enhance these properties, as well as improve aspects such as flexibility, material waste, resolution improvement, and the finest control of surface functionalization. Even though a wide range of examples has multiplied in the literature over the past decade, to date, most of them still lack uniformity or detailed guidance regarding both the fabrication process and the metrological characterization procedure. With this in mind, this review aims to serve as a guideline for the identification of project specifications for the design, fabrication, and test of ion-selective all-solid-state printed sensors, as well as to propose a common metric in characterizing these devices.
