The term nanoelectronics refers to the use of nanotechnology in electronic mechanisms. It is further described as the science that deals with the electronic components designed and engineered at a molecular level. The size of these components is critical and often measured in nanometers. As the components become tinier, they get harder to manufacture.
The materials and devices used in nanoelectronics are generally very small and can establish an interatomic interaction, thereby, the quantum mechanical properties of these materials need to be studied extensively.
Nanotechnology plays a vital role in the field of electronics. It provides a faster, smaller, and more portable device. This technology has a very broad-ranging application such as in the development of nanotransistors, nanosensors, nanorobotics, nanowires, and nanocomputing.
Robotics and Nanorobotics
Robotics refers to the design, construction, operation, and application of robots.
Nanorobotics is the technology of creating machines or robots at or close to the scale of a nanometer (10-9 meters). It can also be defined as a computer-controlled robotic device made up of nanoscale components to molecular precision and is microscopic. These devices have various names such as nanobot, nanoid, nanite, nanomachine, or nanomite.
Current developments in nanoelectronics and nanobiotechnology are providing viable advances that enable the development of molecular devices, which comprise of sensors, actuation, data transmission, remote control uploading, and coupling power supply subsystems, focusing on the basics for the operation of medical nanorobots.
Nanoelectronics is comprehensively used in advance medicine to offer details on the teleoperated techniques and equipment design methodology required for the effective development of nanorobots.
Nanoelectronics Make Superior Robots
The development of nanoelectronics means shrinking computer components, not just device cases. Tiny processors and chips allow for greater memory and functionality within the device. The robots developed are more capable and intelligent. The advances to the size and performance of the batteries allow the devices to perform more efficiently for longer.
Nanoelectronic Circuits for Millimeter-Scale Walking Robots
A novel nanoelectronic digital logic circuit was engineered to control a millimeter-scale walking robot using a nanowire circuit architecture. Simulations were carried out using a SPICE circuit simulator. Unique device models were constructed to assess the function and integrity of the nanoelectronic circuit’s output. This nanoelectronic circuit has many advantages that include- a) extremely small size and b) relatively low power consumption.
Application and Advantages of Nanorobots
Nanorobotics has a varied range of applications. In the field of medicine, nanorobots are predominantly used for the removal of kidney stones, treatment of cancer, elimination of the defected part in a DNA structure, treatment and diagnosis of diabetes, dental treatment, gene therapy, etc.
The main advantages of this technology include the reduction in the risk of surgery, minimization in the cost of surgery, and the ease of operation. Further, the thin, strong layers of nanomaterials improve the durability of machines. The use of nanorobot for medical defense is an effective way to prevent an aggressive pandemic disease to blowout into an outbreak. The research and development of nanorobots in fields such as medicine and defense technology should lead us to a safer and healthier future.
