Electronics Grow on Trees Thanks to Nanocellulose Paper Semiconductors

Semiconducting nanomaterials with 3D network structures have high surface areas and lots of pores that make them excellent for applications involving adsorbing, separating, and sensing. However, simultaneously controlling the electrical properties and creating useful micro- and macro-scale structures, while achieving excellent functionality and end-use versatility, remains challenging.

Thin film to stimulate retinal tissue

Using electric signals to stimulate tissues is the basis of several medical devices such as pacemakers for the heart or neurostimulators used for patients suffering from epileptic fits. A research team has developed a photoelectric dye-coupled thin film device that generates electric potential changes when exposed to light. In their latest study, the research team reveals the ability of this device in stimulating degenerated retinal tissues.

True 2 Materials

True 2 Materials specialise in the production process and downstream integration of graphene and other nanomaterials. IDTechEx technology analyst Dr Richard Collins interviewed Richard Carlow (CEO).

A cool approach to flexible electronics

A nanoparticle ink that can be used for printing electronics without high-temperature annealing presents a possible profitable approach for manufacturing flexible electronics.

Transistors with organic thin-film of alkyl-substituted picene

Study has shown that using phenacene-type molecules in transistors would be a promising solution to lead next generation devices such as flexible displays and flexible IC tags.

Organic thin-film transistors through room-temperature printing

A research team succeeded in establishing a process to form organic thin-film transistors, conducting the entire printing process at room temperature under ambient atmospheric conditions.

Graphene moves beyond the hype at the Graphene LIVE! USA Event

The Graphene LIVE! USA event has lined up top-class speakers for its business-orientated conference and tradeshow on graphene.

Colloidal Ink Co., Ltd

Colloidal Ink is a recently formed spin-out from Okayama University. IDTechEx awarded Colloidal Ink the best Technical Development Materials Award at its Printed Electronics Conference (Europe) 2013. Colloidal Ink has developed a patented and promising formulation technology which enables rapid sintering of conductive nano inks at room temperature. They have so far demonstrated their conductive paints using gold nanoparticles and are also developing nano silver in their pipeline. Their samples today are conductive paints and the formulation will have to be modified to create screen- or inkjet- printable inks. Colloidal Ink is now in the sample distribution mode.
