DO VLSI DESIGN FOR MULTI-SENSOR SMART SYSTEMS IS EFFECTIVE: A REVIEW BASED STUDY

The electronic industry has been looking for innovative solutions to solve these restrictions with optimum efficiency as power usage and chip size have decreased. Carbon nanotubes (CNTs) have been proposed for use in VLSI design due to their highly attractive electrical and thermal properties. CNTs are graphene sheets that have been rolled into hollow cylinders. They are divided into two categories: single-walled (SWNTs) and multi-walled (MWNTs). SWNTs have a single shell or wall with a diameter of 0.4 to 4 nm, while MWNTs have several concentric shells with a diameter of many nanometers to tens of nanometers. Sensors are becoming increasingly important in a variety of fields, including healthcare. As a result, developing low-cost, miniaturised sensors that are highly selective and responsive, as well as monitor and analysis on a single chip, is highly desirable. The EMG PR methodology is commonly utilised in real-time Human-Machine Interface systems, as previously mentioned (HMI). However, there is yet to be any widespread usage of clinically viable EMG-based robots published. The possible issue is that in order to understand the existing trend, a full pipeline must be completed, including sensing, signal delivery, and refining. Microelectromechanical systems (MEMS) may be used to incorporate these types of sensors, and since they are fabricated on a semiconductor substrate, external signal processing circuitry can be conveniently inserted into the chip, allowing for additional features including multiplexing and analog-to-digital conversion. CNTs have a lot of potential as a base material for VLSI component design. Chemical modifications to carbon nanotubes enable designers to increase the selectivity of electrical properties for various applications.
