“…Material selection is of vital importance in sensor performance; conductive electrodes can be printed with Ag [ 11 , 13 , 14 , 15 , 16 ] or PEDOT:PSS [ 17 ] and flexible substrates utilized can be PI (Kapton) [ 10 , 14 , 15 , 18 , 19 ], PET [ 16 , 20 , 21 , 22 ], polyester-based [ 23 , 24 ], paper [ 12 , 17 ]; or rigid, such as glass [ 25 ] or ceramic [ 26 ]; this is directly correlated to the printing technique. A hybrid approach has been proposed by numerous research groups, where the conductive electrodes are not printed but traditionally patterned and the sensing layer is printed on top [ 19 , 26 , 27 , 28 ].…”

“…Surface acoustic waves (SAW) have been proven to assist both absorption and desorption of sensors developed on piezoelectric substrate; more specifically, 1 kHz waves used with sensors developed on LiNbO 3 substrate with different PEDOT: PSS-based sensing materials yielded good response for a wide range of relative humidity (0–90% RH) [ 27 , 28 ]. Paper-based resistive humidity sensors have also been recently presented; these devices utilize cellulose electrical properties modification by high water molecule absorption [ 12 , 17 ]; this approach provides a very cost-effective design guideline, where mass production of low-cost devices is enabled by simply patterning commercial paper with a conductive ink ( Figure 8 a,b). Additionally, a paper-based sensor consisting of inkjet-printed graphene oxide sensing on screen-printed graphene electrodes was demonstrated, with a response time of 6.5 and 2.4 s, respectively [ 31 ].…”

“…Humidity sensors nominally share a common strategy: electrode deposition with a printing technique such as inkjet [ 12 , 17 , 20 , 35 , 36 , 39 , 40 , 45 ], screen [ 10 , 13 , 15 , 16 , 21 , 24 , 25 , 32 , 43 ] or gravure [ 14 , 38 , 44 ], or a traditional process such as lithography [ 26 , 27 , 28 , 37 ], followed by a sensing layer deposition either via inkjet [ 22 , 23 , 40 ], screen [ 15 , 18 , 25 , 32 , 43 ], gravure [ 10 , 13 , 16 , 21 , 44 ], spin coating [ 27 , 28 , 37 , 38 ] or drop casting [ 14 , 19 , 26 ]. Some groups have presented an approach where the substrate acts as a sensing layer [ 12 , 17 , 34 , 35 , 36 , 45 , 87 ] thus eliminating the need for an additional step of deposition of such layer, while humidity sensors can either provide a resistive...…”

“…Temperature sensors usually exploit a specific material’s thermal properties, and more specifically thermal coefficient of resistance (TCR), thus requiring only one material for sensor development. Various works utilize inkjet or screen-printed silver [ 17 , 40 , 57 , 58 , 59 , 60 ], PEDOT: PSS (pristine or in combination with graphene or CNTS) [ 17 , 46 , 47 , 48 , 52 , 55 , 56 ] amongst other materials which exhibit either positive or negative TCR. Mechanical deformation sensors analyzed in this review have the largest diversity both in terms of material selection and technologies required for manufacturing.…”

Printing technologies have been attracting increasing interest in the manufacture of electronic devices and sensors. They offer a unique set of advantages such as additive material deposition and low to no material waste, digitally-controlled design and printing, elimination of multiple steps for device manufacturing, wide material compatibility and large scale production to name but a few. Some of the most popular and interesting sensors are relative humidity, temperature and strain sensors. In that regard, this review analyzes the utilization and involvement of printing technologies for full or partial sensor manufacturing; production methods, material selection, sensing mechanisms and performance comparison are presented for each category, while grouping of sensor sub-categories is performed in all applicable cases. A key aim of this review is to provide a reference for sensor designers regarding all the aforementioned parameters, by highlighting strengths and weaknesses for different approaches in printed humidity, temperature and strain sensor manufacturing with printing technologies.

complicated, time and energy-consuming, relatively expensive, and produce a large amount of waste materials (washingcleaning-disposal requirements). [8] Thus, much effort has been put toward inventing new techniques for direct printing and additive manufacturing of electronics on desired flexible and rigid substrates, [9][10][11][12][13][14][15][16][17][18] such as polyimide and polyethylene terephthalate (PET). [19][20][21] Different fabrication strategies have been proposed for additive nanomanufacturing of electronics. [22][23][24][25][26][27] The most common direct-write technologies in the field of printed electronics are inkjet printing (IJP) and aerosol jet printing (AJP). [6,[28][29][30][31][32] These technologies allow the precise deposition of liquids containing functional materials. Recently, Patil et al. printed silver (Ag) nanowires (resistance < 50 Ω sq −1 ) on flexible substrates via inkjet printing. [33] Gilshtein et al. demonstrated inkjet-printed indium tin oxide (ITO) patterns with a resistivity of 3.1 × 10 −3 Ω cm on soda-lime glass. [34] Chen et al. showed aerosol jet printing of Ag with a sheet resistance of 1.13 × 10 −2 Ω m −2 on cellulose fiber paper substrate. [31] However, the current ink formulations used in IJP and AJP processes make device fabrication more complicated because they require toxic solvents and additives that limit the substrate's compatibility and hinder the device's performance. [35,36] Also, nozzle clogging in IJP is a common and extremely complex phenomenon. [37] Furthermore, to guarantee a high conductivity of the printed structures, AJP usually requires a high sintering temperature (e.g., ≈280 °C) and a long sintering time (e.g., 12 h on a glass substrate). This limits the AJP to only a few types of substrates. [31] As a result, a new direct printing and patterning method is needed to overcome the challenges. Moreover, the new printing and patterning methods also need to be capable of printing structures with good reliability under repeated mechanical bending and unbending processes.Motivated by these challenges, here, we demonstrated a novel additive nanomanufacturing (ANM) technique recently developed in our lab for manufacturing FHEs and sensors by printing conductive Ag and ITO on different flexible platforms such as polyimide and PET substrates. Conductive Ag is typically used to print electronic tracks, electrodes and antennas. [38,39] Transparent conductors such as ITO are utilized in the printing of components such as flexible strain sensors, solar cells, and organic light-emitting diodes (OLEDs). [40][41][42][43] The growing demand for flexible and wearable hybrid electronics has triggered the need for advanced manufacturing techniques with versatile printing capabilities. Complex ink formulations, use of surfactants/contaminants, limited source materials, and the need for high-temperature heat treatments for sintering are major issues facing the current inkjet and aerosol printing methods. Here, the nanomanufacturing of flexible hybrid electronics (FHE) by...
