Tiny Magnetic Particles Enable New Material to Bend, Twist, and Grab
By Josh Brown – A team of researchers from the Georgia Institute of Technology and The Ohio State University has developed a soft polymer material, called magnetic shape memory polymer, that uses magnetic fields to transform into a variety of shapes. The material could enable a range of new applications from antennas that change frequencies on the fly to gripper arms for delicate or heavy objects.
The material is a mixture of three different ingredients, all with unique characteristics: two types of magnetic particles, one for inductive heat and one with strong magnetic attraction, and shape-memory polymers to help lock various shape changes into place.
“This is the first material that combines the strengths of all of these individual components into a single system capable of rapid and reprogrammable shape changes that are lockable and reversible,” said Jerry Qi, a professor in the George W. Woodruff School of Mechanical Engineering at Georgia Tech. more>

Artificial intelligence development is changing how industry works
By StevenH – Many industries are going to benefit from artificial intelligence development. It’s hard to say which ones in the long term will find the highest level of success, but we can already see significant benefits in a host of industries.
At its core, artificial intelligence is a tool that can acquire, organize and analyze vast amounts of data to create and parameterize models to recognize patterns and make predictions. AI is delivering many benefits and its continued use is the key to making a business more competitive. By automating some of the repetitive, basic tasks, a company can increase productivity, reduce mistakes and enable quicker, better decisions. In insurance, for example, companies are using AI to automate claims processing. The entertainment industry uses AI to optimize streaming services and suggest content based on an individual’s previous choices and comparing it to the choices of others.
If you’re a business or a company wondering about what to do about AI, whether to use it or even when to use it, then the answer is, Yes. Businesses must think about using AI. Artificial intelligence is a practical tool, and just like banks use it to prevent fraud or healthcare uses its algorithms to scan X rays, companies should look to solve problems and challenges with AI.
In engineering and manufacturing, artificial intelligence is already enhancing the scheduling in a factory by improving downtime and conducting predictive maintenance scheduling. Artificial intelligence saves companies money by reducing costs, for example by collecting data from running machines in the factory and feed it into training for predictive maintenance AI models.
Manufacturers can use these models to detect signs that maintenance is needed, such as changes in vibration signals which might indicate there is a developing problem. They can then schedule a maintenance session at the downtime of their choosing, perhaps overnight on a Saturday where there could be minimal or no loss of production. Naturally, it’s more economical to perform maintenance at the company’s discretion than having an expensive machine offline for several days, while possibly waiting for delivery of replacement parts from somewhere on the other side of the world. more>

Meet your virtual avatar: the future of personalized healthcare
ITU News – Tingly? Sharp? Electric? Dull? Pulsing?
Trying to describe a pain you feel to your doctor can be a difficult task. But soon, you won’t have to: a computer avatar is expected to tell your doctor everything they need to know.
The CompBioMed Centre of Excellence, an international consortium of universities and industries, is developing a program that creates a hyper-personalized avatar or ‘virtual human’ using a supercomputer-generated simulation of an individual’s physical and biomedical information for clinical diagnostics.
There is a rapid and growing need for this kind of technology-enabled healthcare. 12 million people who seek outpatient medical care in the U.S. experience some form of diagnostic error. Additionally, the World Health Organization estimates that there will be a global shortage of 12.9 million healthcare workers by 2035.
Greater access to technology-enabled healthcare will allow doctors to make better and faster diagnoses – and provide the tools to collect the necessary data.
The Virtual Human project combines different kinds of patient data that are routinely generated as part of the current healthcare system, such as x-rays, CAT scans or MRIs to create a personalized virtual avatar. more>

Tiny Vibration-Powered Robots Are the Size of the World’s Smallest Ant
By John Toon – Researchers have created a new type of tiny 3D-printed robot that moves by harnessing vibration from piezoelectric actuators, ultrasound sources or even tiny speakers. Swarms of these “micro-bristle-bots” might work together to sense environmental changes, move materials – or perhaps one day repair injuries inside the human body.
The prototype robots respond to different vibration frequencies depending on their configurations, allowing researchers to control individual bots by adjusting the vibration. Approximately two millimeters long – about the size of the world’s smallest ant – the bots can cover four times their own length in a second despite the physical limitations of their small size.
“We are working to make the technology robust, and we have a lot of potential applications in mind,” said Azadeh Ansari, an assistant professor in the School of Electrical and Computer Engineering at the Georgia Institute of Technology. “We are working at the intersection of mechanics, electronics, biology and physics. It’s a very rich area and there’s a lot of room for multidisciplinary concepts.”
A paper describing the micro-bristle-bots has been accepted for publication in the Journal of Micromechanics and Microengineering. The research was supported by a seed grant from Georgia Tech’s Institute for Electronics and Nanotechnology. In addition to Ansari, the research team includes George W. Woodruff School of Mechanical Engineering Associate Professor Jun Ueda and graduate students DeaGyu Kim and Zhijian (Chris) Hao. more>
