Flexible electronics have enabled the design of sensors, actuators, microfluidics and electronics on flexible, conformal and/or stretchable sublayers for wearable, implantable or ingestible applications. However, these devices have very different mechanical and biological properties when compared to human tissue and thus cannot be integrated with the human body.

A team of researchers at Texas A&M University has developed a new class of biomaterial inks that mimic native characteristics of highly conductive , much like skin, which are essential for the ink to be used in 3D printing.

This biomaterial ink leverages a new class of 2D nanomaterials known as molybdenum disulfide (MoS2). The thin-layered structure of MoS2 contains defect centers to make it chemically active and, combined with modified gelatin to obtain a flexible hydrogel, comparable to the structure of Jell-O.

The private space firm hopes to send a small probe to Venus by 2023.

Rocket Lab is self-funding a mission to go to Venus in search of signs of extraterrestrial life, a report from *Ars Technica* reveals.

Venus’s surface is a hellish landscape with crushing pressures and temperatures that make it completely uninhabitable. However, some scientists believe the clouds above Venus’ surface may have conditions that are conducive to some forms of microbial life.

How intelligent can robots get?Robots are getting smarter, which means they are better able to execute our commands. A number of different companies worldwide focus their attention on creating robots but one company in particular is really taking the lead on this lofty goal: Google.


Giving a robotic assistant a broad-based understanding of how to be helpful at home or work isn’t easy. But Google researchers are making progress.

In Part 1 of this who-knows-how-many-parts-there-will-be mini-series, we focused on one of my favorite display technologies in the form of Nixie tubes. We also featured a photograph showing the main control room of an abandoned power plant in Hungary that—much like your humble narrator—was simply oozing with style.

In that photograph, you may have spotted another of my favorite display technologies—vintage analog meters—which I typically acquire at Hamfests and electronic flea markets. I really like the look and feel of these little beauties so long as they are of a certain age, thereby bestowing an air of gravitas upon the occasion of their use.

One of my ongoing hobby projects is what I call my Vetinari Clock, which is named after one of the characters from Terry Pratchett’s Discworld series. Lord Havelock Vetinari, who is the Lord Patrician in charge of the city-state of Ankh-Morpork, has a strange clock in his waiting-room. While it does keep completely accurate time overall, it sometimes ticks and tocks out of sync (for example, “tick, tock … ticktocktick, tock …”) and it occasionally misses a ‘tick’ or a ‘tock’ altogether. As a result, by the time Lord Vetinari’s visitors are finally granted an audience, their nerves are already frayed and frazzled.

This new invention is highly scalable since its raw materials are commercially available and easy to access.

A team of researchers from the National University of Singapore’s (NUS) College of Design and Engineering (CDE) has developed a self-charging electricity generation (MEG) device that generates electricity from air moisture, according to a press release by the institution.


Imagine being able to generate electricity by harnessing moisture in the air around you with just everyday items like sea salt and a piece of fabric, or even powering everyday electronics with a non-toxic battery that is as thin as paper. A team of researchers from the National University of Singapore’s (NUS) College of Design and Engineering (CDE) has developed a new moisture-driven electricity generation (MEG) device made of a thin layer of fabric — about 0.3 millimetres (mm) in thickness — sea salt, carbon ink, and a special water-absorbing gel.

The concept of MEG devices is built upon the ability of different materials to generate electricity from the interaction with moisture in the air. This area has been receiving growing interest due to its potential for a wide range of real-world applications, including self-powered devices such as wearable electronics like health monitors, electronic skin sensors, and information storage devices.
