“…The choice of the graphene/PEDOT:PSS composite was done based on previous case studies that were performed in our lab that shed light on the electrical properties of the ink and the potential for stretchable applications3031. The compatibility of the ink composite (Innophene Phene plus I3015) for inkjet printing was also studied independently by other groups, providing further rationale for the ink’s suitability for our needs32.…”

Epidermal electronic systems (EESs) are skin-like electronic systems, which can be used to measure several physiological parameters from the skin. This paper presents materials and a simple, straightforward fabrication process for skin-conformable inkjet-printed temperature sensors. Epidermal temperature sensors are already presented in some studies, but they are mainly fabricated using traditional photolithography processes. These traditional fabrication routes have several processing steps and they create a substantial amount of material waste. Hence utilizing printing processes, the EES may become attractive for disposable systems by decreasing the manufacturing costs and reducing the wasted materials. In this study, the sensors are fabricated with inkjet-printed graphene/PEDOT:PSS ink and the printing is done on top of a skin-conformable polyurethane plaster (adhesive bandage). Sensor characterization was conducted both in inert and ambient atmosphere and the graphene/PEDOT:PSS temperature sensors (thermistors) were able reach higher than 0.06% per degree Celsius sensitivity in an optimal environment exhibiting negative temperature dependence.

“…The PEDOT:PSS/graphene ink has a solid content of 0.6 wt-%, its viscosity is 7.2 mPas and the conductivity is given as 300 S/cm. The graphene flakes are homogeneously dispersed in the polymer matrix [27]. For some PEDOT:PSS/graphene samples ultrasonication (Elma S120H Elmasonic 1000 W, 90 minutes) was used on the ink before applying it on the substrate.…”

“…Further, the solution processability of graphene/PEDOT:PSS allows for low-cost and high throughput fabrication making it interesting material for flexible and transparent optoelectronic devices such as a flexible display, solar cell and sensors. For example, printed graphene/PEDOT:PSS films have been used as stretchable [27] and transparent [28,29] electrodes.…”

Measuring optical anisotropy in poly(3,4-ethylene dioxythiophene):poly(styrene sulfonate) films with added graphene Isoniemi, Tommi; Tuukkanen, Sampo; Cameron, David C.; Simonen, Janne; Toppari, Jussi Isoniemi, T., Tuukkanen, S., Cameron, D. C., Simonen, J., & Toppari, J. (2015). Measuring optical anisotropy in poly (3,4-ethylene AbstractGraphene is a 2D nanomaterial having a great potential for applications in electronics and optoelectronics. Composites of graphene with conducting polymers have shown high performance in practical devices and their solution-processability enables low-cost and high-throughput mass manufacturing using printing techniques. Here we measure the effect of incorporation of graphene into poly(3,4-ethylene dioxythiophene):poly(styrene sulfonate) (PEDOT:PSS) to the optical anisotropy, absorbance and conductivity of the film. Uniaxial anisotropy in PEDOT:PSS films has been thought to be caused by the spin-coating process used in fabrication. We have characterized spray-and spincoated films using ellipsometry and total internal reflection spectroscopy, the latter especially for films too thick and uneven for ellipsometry, and show that spray-coating, similar to inkjet printing, also produces consistently anisotropic properties even in very thick and uneven films. Possible plasmonic excitations related to graphene are not seen in the films. The optical and electrical anisotropy of graphene/PEDOT:PSS enables routes to high performance devices for electronics, photonics and optoelectronics.

“…This molecular structure is responsible for amazing mechanical properties: Carbon nanotubes are presently among the strongest and stiffest known materials with a nominal Young's modulus [47,71] of 1 TPa and ideal strength greater than 100 MPa [3]. In addition, they are electrically and thermally conductive, chemically sensitive, transparent, and light weight [72]. Nanotubes can be visualized as the result of rolling up a patch of a regular hexagonal lattice.…”

Carbon nanotubes are modeled as point configurations and investigated by minimizing configurational energies including two-and three-body interactions. Optimal configurations are identified with local minima and their fine geometry is fully characterized in terms of lower-dimensional problems. Under moderate tension, we prove the existence of periodic local minimizers, which indeed validates the so-called Cauchy-Born rule in this setting.2010 Mathematics Subject Classification.
