U.S. Air Force scientists developed liquid metal which autonomously changes structure

 As reported by the U.S. Air Force Research Laboratory, military scientists have developed a “Terminator-like” liquid metal that can autonomously change the structure, just like in a Hollywood movie.

The scientists developed liquid metal systems for stretchable electronics – that can be bent, folded, crumpled and stretched – are major research areas towards next-generation military devices.

Conductive materials change their properties as they are strained or stretched. Typically, electrical conductivity decreases and resistance increases with stretching.

The material recently developed by Air Force Research Laboratory (AFRL) scientists, called Polymerized Liquid Metal Networks, does just the opposite. These liquid metal networks can be strained up to 700%, autonomously respond to that strain to keep the resistance between those two states virtually the same, and still return to their original state. It is all due to the self-organized nanostructure within the material that performs these responses automatically.

“This response to stretching is the exact opposite of what you would expect,” said Dr. Christopher Tabor, AFRL lead research scientist on the project. “Typically a material will increase in resistance as it is stretched simply because the current has to pass through more material. Experimenting with these liquid metal systems and seeing the opposite response was completely unexpected and frankly unbelievable until we understood what was going on.”

Wires maintaining their properties under these different kinds of mechanical conditions have many applications, such as next-generation wearable electronics. For instance, the material could be integrated into a long-sleeve garment and used for transferring power through the shirt and across the body in a way that bending an elbow or rotating a shoulder won’t change the power transferred.

AFRL researchers also evaluated the material’s heating properties in a form factor resembling a heated glove. They measured thermal response with sustained finger movement and retained a nearly constant temperature with a constant applied voltage, unlike current state-of-the-art stretchable heaters that lose substantial thermal power generation when strained due to the resistance changes.

This project started within the last year and was developed in AFRL with fundamental research dollars from the Air Force Office of Scientific Research. It is currently being explored for further development in partnership with both private companies and universities. Working with companies on cooperative research is beneficial because they take early systems that function well in the lab and optimize them for potential scale up. In this case, they will enable integration of these materials into textiles that can serve to monitor and augment human performance.

The researchers start with individual particles of liquid metal enclosed in a shell, which resemble water balloons. Each particle is then chemically tethered to the next one through a polymerization process, akin to adding links into a chain; in that way all of the particles are connected to each other.

As the connected liquid metal particles are strained, the particles tear open and liquid metal spills out. Connections form to give the system both conductivity and inherent stretchability. During each stretching cycle after the first, the conductivity increases and returns back to normal. To top it off, there is no detection of fatigue after 10,000 cycles.

“The discovery of Polymerized Liquid Metal Networks is ideal for stretchable power delivery, sensing and circuitry,” said Capt. Carl Thrasher, research chemist within the Materials and Manufacturing Directorate at AFRL and lead author on the Journal Article. “Human interfacing systems will be able to operate continuously, weigh less, and deliver more power with this technology.”

“We think this is really exciting for a multitude of applications,” he added. “This is something that isn’t available on the market today so we are really excited to introduce this to the world and spread the word.”

The Future of .....

Invasive Brain-Computer Interfaces (BCIs) allow users to control a computer via electrodes that have been implanted into their brain.

Current models are limited due to the fact that they are made out of rigid material — the brain is soft, while implants are not.

Now, two researchers argue that neurotechnology is on the cusp of a major breakthrough with ultra-flexible brain-machine interfaces.

Rigid electronics

"The brain is squishy and these implants are [typically] rigid," Shaun Patel, a faculty member at the Harvard Medical School and Massachusetts General Hospital, said in a press release.

About four years ago, however, he discovered Charles M. Lieber's ultra-flexible alternatives. Now, he believes these are the future of BCIs.


 In a recent perspective titled "Precision Electronic Medicine," published in Nature Biotechnology, Patel and Lieber, a Joshua and Beth Friedman University Professor, argue that 'neurotechnology' is on the verge of breaking through the issue of rigid devices.

"The next frontier is really the merging of human cognition with machines," Patel said. "Everything manifests in the brain fundamentally. Everything. All your thoughts, your perceptions, any type of disease," he continued.

Electrodes can also be used to help with diseases such as Parkinson's. If drugs don't work, FDA-approved electrodes can provide relief of tremors through Deep Brain Stimulation.

Over time, however, the brain's immune system treats the rigid implants as foreign objects, often reducing the device's ability to treat the patient.

Mesh electronics

Lieber's mesh electronics, on the other hand, provoke almost no immune response. What's more, they collect data over time that can help improve how these devices work and treat patients.


These types of devices could be used without the prominent side effects of more typical BCIs and electrode devices.

Patel isn't shy about saying he thinks this work could provide a major breakthrough.

"The potential for it is outstanding," Patel said. "In my own mind, I see this at the level of what started with the transistor or telecommunications."

The potential is, in fact, highly impressive. Adaptive electrodes, for example, could have the ability to improve control of prosthetic or even paralyzed limbs.


Mesh electronics and BCIs, however, are technologies still in their early stages.

Companies like Elon Musk's Neuralink are also working on the technology. Musk, who famously sets very ambitious deadlines for his products, said "it will take time" to develop their technology.
