Cyborg beetles can be used to detect chemical weapons and monitor the environment

DailyTechInfo based on IEEE Spectrum: Cyborg Beetles Detect Nerve GasResearchers from South Korea have created tiny flexible electronic devices, the synthesis of which can be performed in one technological step and which can be attached to various living beings, including insects and plants.

Transformed into cyborgs, these living creatures can act as living sensors capable of detecting various chemicals and monitoring the state of the environment.

The main achievement of scientists from South Korea is not the creation of cyborgized creatures, this possibility is only one of the areas of application of the technology they have developed. Scientists, with the help of various catalysts, have learned to synthesize quite complex electronic circuits, including transistors, electrodes, antennas and sensors, all elements of which consist exclusively of carbon of monatomic thickness, graphene and carbon nanotubes.

All the properties of carbon nanotubes and graphene known to scientists today are used in the designs of the electronic devices being created. By giving carbon the necessary shape, scientists have achieved the appearance of clearly defined semiconductor properties in the carbon nanotube material, and the high specific electrical conductivity of graphene allows it to be used as a material for electronic connections.

Any carbon electronic device necessarily includes a specialized antenna that "catches" radio waves and directs their energy to the device. Thus, such devices can function in any conditions without requiring a built-in or external power supply. In addition, the aforementioned antenna is also used for its intended purpose – to receive commands to the device from the outside and to transmit the data collected by the device.

Korean scientists from the Ulsan National Institute of Science and Technology (UNIST) and the Korea Electrotechnology Research Institute (Korea Electrotechnology Research Institute) have demonstrated that their fully carbon electronic devices can be placed on almost any surface, including the surface of plants, the chitinous shell of insects, paper, fabric and human skin. It does not require the use of special adhesives, the thinnest carbon film is securely attached to the surface due to the forces of molecular attraction.

As an example of the developed technology, scientists have created a tiny sensor capable of detecting a very small concentration of DMMP vapors, a substance used in the production of certain chemical warfare agents such as sarin and soman. But the researchers claim that their technology makes it possible to create practically any type of sensors that can monitor temperature, humidity, detect pollution and the presence of pathogens in the environment. This, combined with the absolute harmlessness of carbon electronics for living beings, opens up huge prospects for its widespread use in a variety of fields.
