Abstract The dissemination of sensors is key to realizing a sustainable, ‘intelligent’ world, where everyday objects and environments are equipped with sensing capabilities advance the sustainability quality our lives—e.g. via smart homes, cities, healthcare, logistics, Industry 4.0, precision agriculture. realization full potential these applications critically depends on availability easy-to-make, low-cost sensor technologies. Sensors based printable electronic materials offer ideal...
In this paper, a woven textile containing temperature and humidity sensors realized on flexible, plastic stripes is presented. The authors introduce two different fabrication techniques: the first one consists of conventional photolithography patterning technique; second one, namely inkjet-printing, here presented as an effective, low-cost alternative. both cases, we obtain that can be easily integrated within fabric by using weaving machine. All are fully characterized performances obtained...

This work presents the simultaneous fabrication of ambient relative humidity (RH) and temperature sensors arrays, inkjet-printed on flexible substrates subsequently encapsulated at foil level. These are based planar interdigitated capacitors with an sensing layer meander-shaped resistors. Their combination allows compensation RH signals variations different temperatures. The whole system is carried out level involves utilization additive methods such as inkjet-printing electrodeposition....
Plastic electronics is an enabling technology for obtaining active (transistor based) electronic circuits on flexible and/or nonplanar surfaces. For these reasons, it appears as a perfect candidate to promote future developments of wearable toward the concept fabrics and garments made by functional (in this case, electronic) yarns. In paper, panoramic view recent achievements perspectives given.

This review first recalls the basic functioning principles of organic electrochemical transistors (OECTs) then focuses on transduction mechanisms applicable to OECTs. Materials constituting active semiconducting part are reviewed, from historical conducting polymers (polyaniline, polypyrrole) actual gold standard, poly-3,4-ethylenedioxythiophene: polystyrene sulfonic acid (PEDOT:PSS), as well methods used fabricate these transistors. The applications OECTs for detection small molecules and...
Stimuli-responsive hydrogels represent a class of materials capable reversibly switching their morphological and physicochemical characteristics. An ultrathin poly(acrylic acid) film (ca. 6 nm) grafted onto the gate p-type EGOFET is studied, correlation between swelling state hydrogel transistor output characteristics presented. The hydrogel-related process occurring in basic medium causes an increase threshold voltage due to abrupt intense negative charge density on electrode. variation...
Abstract When drying a colloidal solution, cracks appear in the resulting film. In certain cases, spontaneous order is observed, and form arrays of periodic patterns. Although this phenomenon might be envisioned as patterning method, overcoming practical challenges necessary to transform it into technological tool for microfabrication.

Au nanoparticles functionalized by short poly(ethylene glycol) chain ligands were suspended in a hydroalcoholic medium. This suspension was then printed inkjet onto Kapton® substrate. Gold electrodes consisting of four stacked layers exhibited conductivity (1 ± 0.1) × 107 S/m, close to that bulk, after low-temperature thermal annealing. The electrochemical behaviour with respect heterogeneous electron transfer reactions and the reactivity towards thiol chemisorption are identical those...
This paper presents the printing of resistive and interdigitated (IDE) capacitive devices for temperature humidity sensing applications, respectively, on biodegradable polylactic acid (PLA) substrates. Inkjet gravure were evaluated to transfer silver-based nanoparticles inks. Flash photonic ink sintering methodologies employed maintain PLA mechanical integrity due its low glass transition (58 °C). Between two techniques investigated, gravure-printed 200 μm-thick sheets shown have better...
.Conductivity and Seebeck coefficient of inkjet-printed PEDOT:PSS thin films were found to depend on the substrate (polyimide, silicon oxide, glass) electrode (e-beam evaporated vs. inkjet-printed). The printing direction was also strongly impact thermoelectric power factor.
