The prospective of using direct‐write printing techniques for the manufacture organic photovoltaics (OPVs) has made these highly attractive. OPVs have potential to revolutionize small‐scale portable electronic applications by directly providing electric power systems. However, no route is available monolithically integrating energy‐harvesting units into a system in which other components, such as transistors, sensors, or displays, are already fabricated. Here, fabrication and measurement...
In this paper, we present a functional integrated plastic system. We have fabricated arrays of organic thin-film transistors (OTFTs) and printed electronic components driving an electrophoretic ink display up to 70 mm by on single flexible transparent foil. Transistor were quickly reliably configured for different logic functions additional process step inkjet printing conductive silver wires poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS) resistors between or blocks....
Understanding body malodour in a measurable manner is essential for developing personal care products. Body the result of bodily secretion highly complex mixture volatile organic compounds. Current measurement methods are manual, time consuming and costly, requiring an expert panel assessors to assign score each human test subject. This article proposes technology-based solution automate this task by custom-designed classification system comprising electronic nose sensor array, readout...
Solution-processed semiconductors such as conjugated polymers have great potential in large-area electronics. While extremely appealing due to their low-temperature and high-throughput deposition methods, integration high-performance circuits has been difficult. An important remaining challenge is the achievement of low-voltage circuit operation. The present study focuses on state-of-the-art polymer thin-film transistors based poly(indacenodithiophene-benzothiadiazole) shows that general...
Integrated circuits based on thin-film transistors (TFTs) are attractive for use in many areas, including the Internet-of-Things (loT), where ultra-thin flexible substrates at a low-cost per unit area provide significant advantages over silicon CMOS. A complete loT circuit TFTs requires complex digital to perform embedded control and signal-processing calculations. In this work, we have demonstrated microprocessor capable of such computations showcase it by running assembly code. We selected...
We present a new and simple way of fabricating ultra-thin flexible organic field-effect transistors circuits by directly peeling them off from conventional SiO2 substrates. The devices show excellent flexibility up to bending radius 1 mm. Free-standing OFETs as thin about 600 nm can also be made in this way. In addition, complementary inverters with gain 100 fabricated the peeling-off method.
The authors present the implementation of two amplifiers in a commercial flexible amorphous Indium Gallium Zinc Oxide (a‐IGZO) thin‐film transistor (TFT) technology: Cherry Hooper (CH) amplifier and 4‐stage common source amplifier.

Flexible electronics is a promising approach to target applications whose computational needs are not met by traditional silicon-based due their conformality, thinness, or cost requirements. A microprocessor critical component for many such applications; however, it unclear whether feasible build flexible processors at scale (i.e., high yield), since very few microprocessors have been reported and no yield data from multiple chips has reported. Also, prior manufactured systems were...
Many emerging flexible electronics [1] applications require hardware-based encryption, but it is unclear if practical encryption possible for due to stringent power requirements of these and high area overheads technologies relative silicon CMOS technologies. In this work, we observe that the lifetime many so small often one key suffices entire lifetime. This means that, instead generating keys round in hardware, can generate offline, store directly on engine post fabrication an on-chip...
