This new artificial skin can sense changes in pressure, heat, and cold. This artificial skin could lead to more advanced prosthetics and robots. (Image credit: RMIT University) Though it’s unpleasant, pain is necessary because it helps keep us s...
To achieve the effect, researchers created a unique Hall-bar-like device of graphene-topological insulator heterostructures. Researchers believe this discovery could be used for applications in spintronic and quantum technologies. (Image credit: CC0 ...
Are we one step closer to the holographic technology found in a galaxy far, far away? (Image credit: Tokyo University) Remember the scene from Star Wars: A New Hope when Princess Leia used holographic technology to ask Obi-Wan Kenobi for help? T...
The nano=scaled tweezers could be used to detect pathogens and early stages of diseases such as Alzheimer's. (Image Credit: Justus Ndukaife, Vanderbilt University) Today's optical tweezers, which use a highly focused laser beam to trap a...

Hayabusa2 deployed three rovers and a lander on the Ryugu asteroid, which collected samples of the asteroid's surface. The return mission has been officially approved to land in Australia on December 6th. (Image Credit: JAXA/Akihiro Ikeshita)&nbs...
The TI-125 is designed for measurement, detection, and sampling tasks for R&D and industrial functions, but can also be utilized for COVID-19 applications as well. (Image credit: Omega) Omega designed its T-120 Series of thermal imaging came...
'This physical property can be used to make more precise measurements, which in turn can lead to advance technology like quantum computers. Quantum laser light shines on to a chemical molecule that needs to be measured. The light then passes thro...
The new system would be ideal for underwater data centers that need to connect with surface networks. The system uses various off-the-shelf components and a Raspberry Pi to act as a modem. (Image credit: KAUST) With Wi-Fi readily available in ou...
The new method of tracking space junk involves using high-powered lasers that detect diffused reflections bouncing back from the debris orbiting up to 36,000 kilometers away. (Image credit: NASA) There’s a good chance that no matter where you a...
Citizen-owned seismometers showed significant reductions of noise around schools and universities in places like Cornwall, UK and Boston, U.S. (Image Credit: Imperial College London) Seismometers measure seismic waves from earthquakes, vol...
IntroductionThis short blog post documents a simple project to measure current in devices that may have low power operation for periods, but possibly have periods of high current draw.I recently needed to monitor the current of a few wireless devices...
I have a ST Micro Nucleo board with a low power microcontroller. The STM32F030R8I'm going to measure its power consumption, to see how well it would do in low power designs.ST has a good power measurement example; called PWR_CurrentConsumption. I...
Mutekimaru has already logged over 780 hours of Pokemon Ruby. (Image Credit: Mutekimaure Channel) I’ve been a huge fan of fish ever since my “Project Goldie" internet controlled fishtank build here on element14. This is a pretty fun way of inte...
This image shows a monolayer WSe2 housing "composite fermions," a quasi-particle created from the interaction between electrons. It's also responsible for the sequence of fractional quantum Hall states. (Image Credit: Cory Dean/Columbia...
This real world example shows how to trigger a RIGOL DS1054Z oscilloscope at a specific point in an i2c communication, and then check signal + data.The DS1054Z comes with i2c functionality. In the past they were options you bought separately. Since 2...
The very first video call took place fifty years ago, which involved using the Picturephone Mod II device. (Image Credit: Chris Harrison/Carnegie Mellon University) Fifty years ago, the first-ever video call took place using AT&T’s Pictureph...
A new prototype from UCLA can translate sign language using a smartphone with 98.63% accuracy. Unlike previous devices, this one is lightweight and inexpensive. (Image credit: UCLA) American Sign Language (ASL) is a difficult language to l...
The diagram shows the conditions that cause the Kohn anomaly to rise in convenient metals (left) and a material is known as a Weyl semimetal (right). (Image Credit: MIT) Researchers at MIT and elsewhere have discovered an exotic physical p...
A small script for the DMM6500 to take a number of measurements, triggered by an external signal.
This can be useful when you're automating a test setup. On a production line, on a binning desk, in a setup with a foot pedal, ...
