Solvent-free Printing of Organic Semiconductor, Insulator, Metal, and Conductor Particles on Flexible Substrates

Sakai M., Okada Y., Horiuchi Y., Suzuki M., Tomiya D., Chiba University, JP

Multi-material and solvent-free printing for printed electronics is developed using toner-type patterning of organic semiconductor, insulator, metal and other con- ductor particles, and the subsequent thin-film formation by ultrasonic sintering. Although conventional toner technology was [...]

Resistive Pressure Sensor with Carbon Nanotube Electrodes towards Flexible Electronics Applications

Palumbo A., Zhang R., Yan K., Yang E.H., Chen S., Hader G., Chang J., Yang E.H., Stevens Institute of Technology, US

Here, we present a flexible and stretchable pressure sensor composed of vertically aligned CNTs (VACNTs) partially embedded in a polydimethylsiloxane (PDMS) substrate. VACNTs were grown via chemical vapor deposition and transferred onto PDMS as a [...]

Torres Arango M.A., Sierros K.A., West Virginia University, US

Innovations in materials and manufacturing are important enablers of new technologies across multiple engineering fields. Additive manufacturing comprises a group of revolutionary fabrication techniques, having as principle the addition of materials layer-by-layer to form a [...]

Inkjet Printed Flexible Electronics on Organic Substrate for Wearable Electronics

Lee H., Ma K., Kennesaw State University, US

Printed electronics have shown tremendous growth in recent years, and the demand for faster, smaller, cheaper, and more efficient printed devices is ever increasing. Inkjet printing is a technology which has demonstrated the ability to [...]

Robust Transparent Glass-fabric Reinforced Plastic (FRP) Films for Flexible Electronics Substrate Platform

Bae B.-S., Im H-G, Jung J., KAIST, KR

To realize the flexible electronics in place of rigid electronics constructing on PCB substrates or glass substrates, robust film substrate with thermal resistance, strength and low thermal expansion should be developed. Specially, some applications of [...]

National Science Foundation’s Organic and Flexible Electronics Programs in the Engineering Directorate

Kaul A.B., National Science Foundation, US

Organic semiconductors display fascinating properties which has enabled their application in low-cost, high-efficiency organic photovoltaics (OPV), as well as in flexible and printed electronics for OLEDs for solid state lighting and displays. In particular, the [...]

Low-temperature laser sintering of the printed nano-silver electrodes for flexible electronics

Gu W., Lin J., Cui Z., Suzhou Institute of Nanotech, Chinese Academy of Sciences, CN

One of the key components in flexible electronics is the flexible electrode. Currently, the most commonly used printable electrode material is nano-silver ink which contains various additives.These additives, however, increase the electrical resistivity of nano-silver [...]
