“…This distinctive property of TE material provides an alternative mechanism for fabricating EFWSs, by converting thermal energy into a voltage to activate a fire alarm during the pre-combustion stage. Traditional TE materials account for solid inorganic semiconductors (Bi, Te, Se, and their based alloys [97,98]), which benefit from excellent TE performance. However, these materials are typically expensive, scarce, toxic, and lack flexibility.…”

“…Furthermore, conductive polymers (CPs) are also promising TE materials. In particular, PEDOT:PSS (poly(3,4-ethylenedioxythiophene):p olystyrene sulfonate)-based composites have demonstrated their high potential as TE material [97,[100][101][102]. To obtain a higher-voltage output, TE materials are often combined in arrays containing p-and n-type TE materials to create thermoelectric generators (TEG), and some systems even work without external power supply [44,103].…”

Early-stage fire-warning systems (EFWSs) have attracted significant attention owing to their superiority in detecting fire situations occurring in the pre-combustion process. Substantial progress on EFWSs has been achieved recently, and they have presented a considerable possibility for more evacuation time to control constant unintentional fire hazards in our daily life. This review mainly makes a comprehensive summary of the current EFWSs, including the working mechanisms and their performance. According to the different working mechanisms, fire alarms can be classified into graphene oxide-based fire alarms, semiconductor-based fire alarms, thermoelectric-based fire alarms, and fire alarms on other working mechanisms. Finally, the challenge and prospect for EFWSs are briefly provided by comparing the art of state of fire alarms. This work can propose a more comprehensive understanding of EFWSs and a guideline for the cutting-edge development direction of EFWSs for readers.

“…Te/polymers have become increasingly attractive in thermoelectrics. In recent years, lots of polymers, for instance, poly (3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) or poly(3,4-ethylenedioxythiophene) (PEDOT), [106][107][108] polyaniline (PANI), 109,110 polypyrrole (PPy), 111,112 poly(3-hexylthiophene) (P3HT), 113 polyvinylpyrrolidone (PVP), 114,115 poly-vinylidene uoride (PVDF), 81 poly(methyl methacrylate) (PMMA), [116][117][118] polyvinyl alcohol (PVA), 119 and epoxy, 120 have been investigated to fabricate Te/polymer NCs.…”

“…As a good example of R2R gravure printed flexible electronics, single-wall carbon nanotube-based thin film transistors (SWCNT-TFTs) have been attracted by many research groups because of specific metrics such as high carrier mobility, excellent chemical stability, and mechanical flexibility [ 4 , 5 , 6 , 7 , 8 ]. In the R2R gravure printed SWCNT-TFTs, however, the formation of a uniform layer is one of the critical factors in achieving the printed devices that are uniform over TFT arrays [ 9 , 10 , 11 , 12 ]. Thus, developing a simple and rapid method for monitoring the devices’ uniformity of the R2R gravure printed products would be valuable and efficient to elucidate the influence of each printed layer of the SWCNT-TFTs while the other printed layers remain unchanged.…”

Rapid Uniformity Analysis of Fully Printed SWCNT-Based Thin Film Transistor Arrays via Roll-to-Roll Gravure Process

The roll-to-roll (R2R) gravure process has the potential for manufacturing single-wall carbon nanotubes (SWCNT)-based thin film transistor (TFT) arrays on a flexible plastic substrate. A significant hurdle toward the commercialization of the R2R-printed SWCNT-TFT array is the lack of a suitable, simple, and rapid method for measuring the uniformity of printed products. We developed a probing instrument for characterizing R2R gravure printed TFT, named PICR2R-TFT, for rapidly characterizing R2R-printed SWCNT-TFT array that can present a geographical distribution profile to pinpoint the failed devices in an SWCNT-TFT array. Using the newly developed PICR2R-TFT instrument, the current–voltage characteristics of the fabricated SWCNT-TFT devices could be correlated to various R2R-printing process parameters, such as channel length, roll printing length, and printing speed. Thus, by introducing a characterization tool that is reliable and fast, one can quickly optimize the R2R gravure printing conditions to enhance product uniformity, thereby maximizing the yield of printed SWCNT-TFT arrays.
