This paper introduces a cost-effective method for the fabrication of stretchable circuits on polydimethylsiloxane (PDMS) using inkjet printing of silver nanoparticle ink. The fabrication method, presented here, allows for the development of fully stretchable and wearable sensors. Inkjet-printed sinusoidal and horseshoe patterns are experimentally characterized in terms of the effect of their geometry on stretchability, while maintaining adequate electrical conductivity. The optimal fabricated circuit, with a horseshoe pattern at an angle of 45°, is capable of undergoing an axial stretch up to a strain of 25% with a resistance under 800 Ω. The conductivity of the circuit is fully reversible once it is returned to its pre-stretching state. The circuit could also undergo up to 3000 stretching cycles without exhibiting a significant change in its conductivity. In addition, the successful development of a novel inkjet-printed fully stretchable and wearable version of the conventional pulse oximeter is demonstrated. Finally, the resulting sensor is evaluated in comparison to its commercially available counterpart.

Printed electronic components offer certain technological advantages over their silicon based counterparts, like mechanical flexibility, low process temperatures, maskless and additive manufacturing possibilities. However, to be compatible to the fields of smart sensors, Internet of Things and wearables, it is essential that devices operate at small supply voltages. In printed electronics mostly silicon dioxide or organic dielectrics with low dielectric constants have been used as gate isolators, which in turn has resulted in high power transistors operable only at tens of volts. Here, we present inkjet printed circuits which are able to operate at supply voltages as low as ≤ 2 V. Our transistor technology is based on lithographically patterned drive electrodes, the dimensions of which are carefully kept well within the printing resolutions; the oxide semiconductor, the electrolytic insulator and the top-gate electrodes have been inkjet printed. Our inverters show a gain of ∼ 4 and 2.3 ms propagation delay time at 1 V supply voltage. Subsequently built 3-stage ring oscillators start to oscillate at a supply voltage of only 0.6 V with a frequency of ∼ 255 Hz and can reach frequencies up to ∼ 350 Hz at 2 V supply voltage. Furthermore, we have introduced a systematic methodology for characterizing ring oscillators in the printed electronics domain, which has been largely missing. Benefiting from this procedure, we are now able to predict the switching capacitance and driver capability at each stage, as well as the power consumption of our inkjet printed ring oscillators. These achievements will be essential for analyzing the performance and power characteristics of future inkjet printed digital circuits.The application domains such as Internet of Things (IoT), smart sensors and wearables may benefit from printed electronics (PE) technology where the devices can be printed onto flexible or rigid substrates. Most of the devices in PE, are based on organic materials and suffer from high supply voltage requirements (> 10 V). 1-3 On the other hand, some examples of low voltage organic devices can also be found in the literature. 2,4-10 The reasons behind the need of high supply voltages is the low carrier mobility of p-type organic materials and low performance of printed or vacuum deposited gate dielectrics that have been used. In addition the scarcity of n-type organic semiconductors and p-type inorganic semiconductors leads to missing complementary circuits in both domains, 11 except their realization in hybrid systems. 2,12 Lithographically patterned ring oscillator structures based on organic field-effect transistors (OFETs) are able to perform at high frequency (200 kHz) but at the same time require high supply voltage (-60 V). printed, based on OFETs operate at high supply voltages (∼ −40 V) with frequencies below 5 Hz. 14,15 An OFET based 11-stage ring oscillator operating at only 3 V supply with a frequency of 1.7 Hz was also reported in literature. 7 By using an complementary design, the frequency was increase...

“…Therefore, the research area of printed electronics (PE) is growing rapidly since the realization of the first complex circuits in the late 1990s. [1][2][3][4][5][6] Currently, most of the devices in PE are based on organic materials; stateof-the-art printed field-effect transistors (FETs) consist of lithographically structured or printed electrodes and a printed organic semiconducting channel. As gateinsulators organic, inorganic, or high-k dielectrics are very popular in organic FET (OFET) structures.…”

Printed electrolyte‐gated oxide electronics is an emerging electronic technology in the low voltage regime (≤1 V). Whereas in the past mainly dielectrics have been used for gating the transistors, many recent approaches employ the advantages of solution processable, solid polymer electrolytes, or ion gels that provide high gate capacitances produced by a Helmholtz double layer, allowing for low‐voltage operation. Herein, with special focus on work performed at KIT recent advances in building electronic circuits based on indium oxide, n‐type electrolyte‐gated field‐effect transistors (EGFETs) are reviewed. When integrated into ring oscillator circuits a digital performance ranging from 250 Hz at 1 V up to 1 kHz is achieved. Sequential circuits such as memory cells are also demonstrated. More complex circuits are feasible but remain challenging also because of the high variability of the printed devices. However, the device inherent variability can be even exploited in security circuits such as physically unclonable functions (PUFs), which output a reliable and unique, device specific, digital response signal. As an overall advantage of the technology all the presented circuits can operate at very low supply voltages (0.6 V), which is crucial for low‐power printed electronics applications.
