ASX Tech Stocks: This Engineering Material Can Think and DroneShield Deploys Technology at US International Airport

  • Researchers have used integrated circuits to create a material that can think and act on mechanical stressors
  • DroneShield’s counter drone system is now in place at a US international airport
  • Altech plans to produce pocket-cell lithium-ion batteries for testing in Perth

Researchers from the US Air Force and Penn State University have developed a material that can “think” and “feel” – a bit like a brain.

The technology is based on integrated circuits, which can perform combinatorial logic: when the material receives external stimuli, it translates the input into electrical information which is then processed to create output signals.

“We have created the first example of an engineering material that can simultaneously sense, think about, and act on mechanical stresses, without requiring additional circuitry to process these signals,” said Ryan Harne, associate professor of mechanical engineering at Penn State.

“The soft polymer material acts like a brain that can receive strings of digital information which are then processed, resulting in new sequences of digital information that can control reactions.”

The next step is to interpret the visual data

The material could use mechanical force to calculate complex arithmetic or sense radio frequencies to communicate specific light signals, among other potential translation examples.

Additionally, Harne says that almost every material around us has the ability to act like its own integrated circuit: being able to “think” about what’s going on around it.

The next step is to improve the substance so that it can interpret visual data in the same way that it “senses” physical signals.

“We’re currently translating that into a way of ‘seeing’ to augment the sense of ‘touching’ that we’ve currently created,” Harne said.

“Our goal is to develop material that demonstrates autonomous navigation through an environment by seeing signs, following them, and deflecting away from opposing mechanical forces, like something walking over it.”

DroneShield has sold and deployed its DroneSentry counter-drone system at a US international airport – but it’s a secret squirrel as they haven’t revealed which one.

The system includes the company’s RfOne long-range passive drone detection sensors integrated with DroneSentry-C2 command and control enterprise software = providing near real-time drone detection, tracking and reporting aiding authorities airports to assess safety and risks throughout the airspace.

“Drones can damage or even bring down a contact airliner,” said Jayde Wilks, sales manager.

“Reports of airport disruptions from drones continue to rise, and the security risk and costs associated with hijackings and flight disruptions can be significant.

“With this deployment and future airport deployments, we look forward to helping address this risk.”

Although the revenue associated with the sale is considered intangible (less than $500,000), it is considered a significant development due to the deployment potentially serving as a gateway to the US civil aviation market of over 5,000 airports.


The battery technology company is expanding its research and development labs in Perth, WA, to enable the production of pocket cell-sized batteries for the next stage of its Silumina Anodes project.

Late last year, the company announced its breakthrough technology of incorporating high-capacity silicon into lithium-ion batteries, resulting in 30% more energy capacity than a lithium-ion battery. only conventional graphite.

When developing new active material for lithium-ion batteries, the cell chemistry is first optimized in smaller format button cells, then gradually expanded to full-size pocket cells to provide more information on electrochemical performance, energy density and safety.

And by having an in-house pocket cell production and testing facility, electrical abuse scenarios – where the cell must operate outside of rated voltage and current limits – can be tested.

Physical and environmental abuse scenarios, where the cell is subjected to extreme temperatures or mechanical deformation, can also be tested.


Wastewater treatment player De.mem has signed a $2.1 million build, own, operate (BOO) contract to, unsurprisingly, build, own and operate a wastewater treatment system that will be deployed at the Givaudan factory site in Singapore.

The new plant will incorporate the company’s proprietary ultrafiltration membrane technology as a key treatment step, combined with its specialty chemicals and other wastewater treatment processes.

“Our BOO model offers convenience and simplicity to customers, while generating recurring and long-term revenue for De.mem,” said CEO Andreas Kroell.

“Our in-house membrane technology and our line of specialty chemicals provide a competitive advantage over our peers.”
