Highly Loaded Mildly Edge‐Oxidized Graphene Nanosheet Dispersions for Large‐Scale Inkjet Printing of Electrochemical Sensors

Hubert Girault, Andreas Stephan Lesch, Horst Pick, Milica Jovic, Victor Costa Bassetto, Yingdi Zhu, Bhawna Nagar

Inkjet printing of electrochemical sensors using a highly loaded mildly edge‐oxidized graphene nanosheet (EOGN) ink is presented. An ink with 30 mg/mL EOGNs is formulated in a mixture of N‐methyl pyrrolidone and propylene glycol with only 30 min of sonicat ...

Dimensional scaling of high-speed printed organic transistors enabling high-frequency operation

Vivek Subramanian

Printed electronics has promised to deliver low-cost, large-area and flexible electronics for mass-market applications for some time; however, so far one limiting factor has been device performance. Over the last decade, great progress has been made in ter ...

All-Printed Electrocorticography Array for In Vivo Neural Recordings

Diego Ghezzi, Laura Ferlauto, Eleonora Borda, Nenad Marjanovic, Fabian Michael Lütolf

Bioelectronic and neuroprosthetic interfaces rely on implanted microelectrode arrays (MEAs) to interact with the human body. Printing techniques, such as inkjet and screen printing, are attractive methods for the manufacturing of MEAs because they allow fl ...

Assembling Ni-Fe Layered Double Hydroxide 2D Thin Films for Oxygen Evolution Electrodes

Hubert Girault, Andreas Stephan Lesch, Victor Costa Bassetto

Continuous hydrothermal flow synthesis (CHFS) of Ni-Fe layered double hydroxide (LDH) leads to waterborne dispersions of 2D nanoplatelets in the range of 10-50 nm in lateral size. Conversion of the as-synthesized LDH nanoplatelet dispersion into inkjet pri ...

Inkjet printing of soft machines

Samuel Schlatter

Soft machines and soft robots are an area of intense research because soft systems are safer to interact with, are better at handling fragile objects, can produce complex shapes with fewer transducers, are robust, and are ideal for wearable applications. H ...

Inkjet printed mesoscopic perovskite solar cells with custom design capability

Frank Nüesch, Jakob Heier, Sina Abdolhosseinzadeh

Customizable solar cells are required for aesthetic indoor and outdoor photovoltaic deployment as well as for the freedom of design of small and portable power supplies. We demonstrate that drop on demand inkjet printing can be used for the fabrication of ...

Inkjet‐Printed Composites for Room‐Temperature VOC Sensing: From Ink Formulation to Sensor Characterization

Jürgen Brugger, Thomas Maeder, Mohammadmahdi Kiaee

The authors report the fabrication and characterization of chemiresistive sensors, composed of a thermoplastic elastomer (TPE), styrene‐ethylene‐ran‐butylene‐styrene, and a high‐structure carbon black (CB) targeted for detecting hydrocarbons at or near roo ...

Inkjet Printing of Complex Soft Machines with Densely Integrated Electrostatic Actuators

Herbert Shea, Samuel Rosset, Samuel Schlatter, Giulio Grasso

A multimaterial inkjet printing method for integrated soft multifunctional machines is reported, combining dense arrays of electrostatic actuators, multilayer electrical routing, and complex networks of microfluidic channels in one printing process. Most a ...

Needle-free delivery of fluids from compact laser-based jet injector

Christophe Moser, Paul Delrot, Jan Krizek

Jet injection devices have been studied and developed for transdermal drug delivery to avoid the use of needles. Due to bulky actuation mechanisms, they are limited to body areas that are easy to reach such as skin. Here, we demonstrate a thin and long liq ...

All-printed low-power metal oxide gas sensors on polymeric substrates

Danick Briand, Saleem Khan

This paper presents a novel approach for the fabrication of miniaturized and fully printed metal-oxide (MOX) gas sensors on a polyimide (PI) substrate by using digital manufacturing of the functional layers, namely aerosol jet and inkjet printing technolog ...
