Scientists fold the Smallest Microchips ever from Graphene

Published

on

New developments from physicists from the University of Sussex could lead to faster electronic gadgets. The physicists have created tiny microchip-like objects using ‘nano-origami.’ They foresee phones as well as computers operating many thousand times faster.

The researchers worked with 2D materials, including graphene. They used structural defects within the materials to build the microchips.

These defects affect the properties of the materials, both nano-mechanical and electronic.

The researchers pinpointed the effects of defects like grain boundaries, collapsed wrinkles, and folded wrinkles using Raman mapping and atomic force microscopy.

Graphene acts as a transistor when some distortions are folded into graphene. Transistors are the basic ingredient of electronics. When a graphene strip is folded like that it acts like a microchip.

The graphene strip in question is around 100 times tinier than normal microchips.

Lead researcher Dr. Manoj Tripathi explains the mechanism: “Instead of having to add foreign materials into a device, we’ve shown we can create structures from graphene and other 2D materials simply by adding deliberate kinks into the structure. By making this sort of corrugation we can create a smart electronic component like a transistor or a logic gate.”

The technique relies on Moore’s Law, a law which stipulates that the total sum of transistors within an integrated circuit doubles every two years.

Academics and leaders in the industry have warned that Moore’s law may not necessarily apply for transistors similar in size to silicon chips.

Graphene is a material that provides a possible alternative to silicon and can help to conserve Moore’s law. The researchers are the first to create a microchip using folded graphene.

Said Professor Alan Dalton: “We’re mechanically creating kinks in a layer of graphene. It’s a bit like nano-origami. Using these nanomaterials will make our computer chips smaller and faster. It is absolutely critical that this happens as computer manufacturers are now at the limit of what they can do with traditional semiconducting technology. Ultimately, this will make our computers and phones thousands of times faster in the future.”

“This kind of technology – ‘straintronics’ using nanomaterials as opposed to electronics – allows space for more chips inside any device. Everything we want to do with computers, to speed them up, can be done by crinkling graphene like this.”

Now the researchers are hopeful for further developments in sustainable technology because this process does not require additional materials and can go on at room temperature. It saves energy.

As the clock ticks down to October 28, 2024, a silent crisis is brewing in the world of healthcare technology. The impending shutdown of 3G networks across Australia is set to impact far more than just outdated mobile phones. Medical experts and consumer advocates are sounding the alarm about the potential risks to hundreds of thousands of medical devices that rely on 3G connectivity for critical functions.

The Australian Communications Consumer Action Network (ACCAN) has labeled the situation a “ticking time bomb,” urging medical authorities to take immediate action. ACCAN CEO Carol Bennett emphasized the gravity of the situation, stating, “Many people are simply unaware that devices like insulin pumps, heart rate monitors, and personal safety alarms may all be impacted by the shutdown of 3G networks by Telstra and Optus. It is a major health risk.”

The scope of the problem is staggering. According to industry estimates, up to 200,000 medical devices could be affected by the 3G network closure. These devices range from life-saving implants to crucial monitoring systems that patients and healthcare providers rely on daily.

The Therapeutic Goods Administration (TGA) has identified several categories of medical devices that may be impacted by the 3G network shutdown, including:

  • Cardiac monitoring devices for resynchronization therapy (CRT)
  • Pacemakers and implantable cardioverter defibrillators (ICDs)
  • Glucose data transmitters for diabetes management
  • Continuous Positive Airway Pressure (CPAP) machines for sleep apnea
  • Telehealth devices for remote patient monitoring
  • Wearable health monitors for various conditions
  • Portable automated external defibrillators (AEDs) for emergency response

The implications of these devices losing connectivity are profound. Patients with implanted cardiac devices may lose the ability to transmit critical data to their healthcare providers. Diabetics relying on continuous glucose monitors could face gaps in their blood sugar management. Sleep apnea sufferers might experience interruptions in their therapy tracking. In emergency situations, the failure of an AED to connect could mean the difference between life and death.

Beyond the devices regulated by the TGA, a host of other health and safety-related products are also at risk. These include personal safety pendants for the elderly, fall detection systems, home security alarms, and GPS tracking devices for vulnerable individuals. The potential for these systems to fail simultaneously creates a perfect storm of risk for those who depend on them most.

The Royal Flying Doctor Service (RFDS) has expressed serious concerns about the impact on rural and remote healthcare. RFDS Chief Information Officer Ryan Klose told a Senate inquiry that the organization relies heavily on 3G for telehealth appointments, security cameras, and clinicians’ duress alarms. “There are a lot of devices out there which are used for critical situations that simply will not be (noticed) until it’s too late,” Klose warned.

The telecommunications industry has been preparing for this transition for years, with major providers like Telstra and Optus planning to switch off their 3G networks on October 28, 2024. TPG Telecom/Vodafone has already decommissioned its 3G network at the beginning of 2024. While these companies have been running information campaigns and offering upgrades to affected customers, the medical device sector presents unique challenges.

One of the primary issues is the lack of a comprehensive registry for medical devices in Australia. Unlike pharmaceuticals, which are tightly regulated and tracked, medical devices fall into a regulatory gray area. This has led to what ACCAN’s Carol Bennett describes as “catastrophic failures historically around surgical mesh, breast implants, and ASR hip implants.”

The problem is compounded by the fact that many affected devices may have been purchased overseas or through online marketplaces. Some products claiming 4G compatibility may not actually work on Australian networks, creating a false sense of security for users.

To address these concerns, consumer advocates are calling for swift and decisive action from regulatory bodies. ACCAN is urging the Therapeutic Goods Administration to require medical device manufacturers and their agents to alert consumers about the impending changes and to implement penalties for non-compliance. They are also calling on the Australian Health Practitioner Regulation Agency (AHPRA) to inform medical practitioners about the changes so they can manage patient care appropriately.

The telecommunications industry is also taking steps to mitigate the impact. Both Telstra and Optus have provided thousands of free or subsidised handsets to disadvantaged customers and are developing contingency plans for those who may be cut off when the networks shut down. However, industry executives admit that despite their best efforts, up to 150,000 phone users could still lose service when 3G goes dark.

The Australian government and industry stakeholders have been working to reduce the number of devices that are not compatible with 4G for emergency calls. This includes addressing the issue of phones that use 4G for regular calls and texts but rely on 3G for emergency calls due to a lack of Voice over LTE (VoLTE) capability.

As the deadline approaches, experts are advising all users of medical devices and health-related technology to take immediate action:

  1. Contact your device manufacturer or healthcare provider to determine if your device will be affected by the 3G shutdown.
  2. If your device is at risk, inquire about upgrade options or alternative solutions.
  3. For mobile phones, text “3” to 3498 to check if your device is 3G-dependent.
  4. Be cautious about using medical devices purchased overseas or online, as they may not meet Australian network requirements.
  5. Stay informed about updates from your telecommunications provider regarding the 3G shutdown.

The impending 3G network closure represents a critical juncture for healthcare technology in Australia. As we move towards more advanced and efficient networks, it is imperative that no patient is left behind. The coming months will be crucial for healthcare providers, device manufacturers, and telecommunications companies to work together to ensure a smooth transition that prioritizes patient safety and continuity of care.

With the clock ticking, the race is on to upgrade, replace, or find alternatives for the hundreds of thousands of medical devices that have silently relied on 3G technology. The success of this transition will be measured not in network speeds or technological advancements, but in the uninterrupted care and safety of those who depend on these life-saving devices every day.
