Australian scientists develop new technology capable of analyzing active chips in electronics without disassembly and detecting invisible faults.
A discovery led by Australian scientists could transform the electronics industry. Researchers have developed a new technology capable of observing the internal workings of active chips without needing to turn off, open, or physically touch the devices.
According to a publication in the IEEE Journal of Microwaves on March 17, the method uses terahertz waves, known as T-rays, to identify microscopic electrical movements within semiconductors. This advancement solves a historical problem in electronic engineering, as current methods typically require disassembly, physical contact, or interruption of device operation.
The project involved researchers from the University of Adelaide, Australia, as well as specialists from the University of Potsdam, Germany. According to Professor Withawat Withayachumnankul, the technique represents an important step towards enabling non-invasive inspections of modern active chips.

How the new T-ray based technology can observe active chips
The new technology uses terahertz radiation to analyze electronic components in operation. This range of the electromagnetic spectrum lies between microwaves and infrared light.
Unlike traditional X-rays, terahertz waves are considered non-ionizing. This makes the technology safer for scientific and industrial applications.
Australian scientists managed to detect small electrical changes within active chips using frequencies close to 275 GHz. The major challenge was capturing extremely weak signals in microscopic regions of semiconductors.
To solve this, the team developed a highly sensitive homodyne quadrature receiver. The equipment can eliminate background noise and identify electron movements at transistor junctions.
In practice, the system functions as a kind of “internal vision” for modern electronics. Key benefits include:
- Monitoring without disassembly
- Real-time operation
- Non-contact inspection
- Detection of hidden faults
- Reduction of component damage
Australian scientists solve an old challenge for the electronics industry
Once a chip is encapsulated within its protection, analyzing what happens internally becomes extremely difficult. This problem has plagued the electronics industry for decades. Most current techniques require physical contact with the circuit or even partial destruction of the component. This makes testing expensive and hinders quick diagnostics.
With the new technology, Australian scientists have demonstrated that it is possible to monitor active chips without interfering with the device’s operation. This advancement could benefit strategic sectors such as artificial intelligence, telecommunications, advanced computing, and autonomous vehicles.
Researcher Chitchanok Chuengsatiansup highlighted that the method could also help in verifying the integrity of critical hardware and identifying compromised components.
Active chips could have much faster and more precise inspection
The global semiconductor industry moves hundreds of billions of dollars annually. Therefore, manufacturers invest heavily in quality control and component inspection.
Even so, many internal faults remain difficult to identify. In several cases, defects only appear after the product reaches the market.
The new technology created by Australian scientists could change this scenario. Since active chips can be analyzed without disassembly, tests tend to become faster and more precise.
Another important factor involves the miniaturization of electronic components. As chips become smaller and more powerful, the difficulty of inspection using traditional methods increases.
Terahertz waves emerge precisely as an alternative for analyzing microscopic structures without causing physical damage. Furthermore, the technique can reduce industrial waste, as many components will no longer need to be destroyed during testing.
New technology could accelerate the creation of safer electronics
Australian scientists believe the discovery will have a direct impact on the development of safer and more efficient electronics.
The ability to monitor active chips in real-time offers a significant advantage for semiconductor manufacturers. Problems can be identified during internal testing.
This could accelerate the creation of components for artificial intelligence, high-performance computing, and advanced networks.
Continuous monitoring can also strengthen digital security in critical equipment. Small internal changes can indicate failures or hardware compromise.
Another highlight is the potential for creating self-diagnostic systems. In the future, electronic devices will be able to monitor their own internal conditions automatically.
Possible benefits include:
- Longer device lifespan
- Reduced maintenance costs
- Increased operational safety
- Lower risk of critical failures
- Improved energy performance
Terahertz waves gain ground among the most promising technologies
Terahertz waves have been gaining prominence in scientific research in recent years. Despite their enormous potential, this spectrum range is still little explored due to the technical complexity involved.
The advance led by Australian scientists reinforces the potential of this technology in industrial and scientific applications. In addition to active chip analysis, THz waves are also studied in medical examinations, security systems, and high-speed communication.
In the study presented by the international team, researchers showed that they were able to monitor structures smaller than the wavelength using conventional terahertz optics. This result demonstrates the high level of sensitivity achieved by the system.
The advance that could transform the future of electronic engineering
The new technology represents an important advance for the electronics and semiconductor sector. For the first time, researchers were able to observe internal electrical movements in encapsulated active chips without interrupting the operation of the devices.
This could change how electronic components will be produced, monitored, and tested in the coming years. Australian scientists believe that future research should further enhance the method’s precision and accelerate large-scale commercial applications.
With increasingly smaller and more complex devices, non-invasive solutions are likely to become essential for the next generation of smart and secure electronics.
