Latest Technical Seminar Topics For Mechanical Engineering (2020)

These are man-made nanoscale crystals used to transport the electrons. When the UV rays put on these crystals, then it will emit light of different colours. It has a separate quantized energy spectrum. It contains a small number of conduction band electrons, valence band holes or the finite number of elementary electric charges.

Lean Manufacturing

It is a methodology that emphasizes reducing the waste material during the manufacturing process while alongside, maximizing productivity. It is also named as lean production or lean and a kind of socio-technical concept that’s used by Toyota Production system and now, used by myriad industries.

Micro Electro Mechanical System (MEMS)

It means a technology that enables mechanical structures to be miniaturized and integrated with electrical circuitry and lead to a single physical device, looks like a system. The “system” signifies that both mechanical and electrical components are working together to apply the desired functionality. It is a combination of the very small electrical and mechanical system.


The term is related to microfabrication techniques. It is a very advanced technology that allows microelements with different dimensions in the range of 1-500µm to be fabricated. It forms micro features at the micro-level with no constraint on the size of the element being machined.

Non-Destructive Testing (NDT)

It is a technique that is used by various companies and industries to evaluate and analyze the properties of a material, elements, structure or system for differences in characteristics or defects in welding and working without any damage to the original parts of the machinery. It is also known as non-destructive examination.


Most frequently, it is a 0.1CC compression ignition engine and also referred to as a diesel engine. It was developed by Richard Gordon. There are various tools needed to construct the nano IC engine such as beck plate, dive washer and so on. No other exotic material is required.

Ocean Thermal Energy

This energy is absorbed by the oceans and derived from solar energy. It is a kind of electrical energy that is produced by utilizing the temperature distinction between the deep cold ocean water and warm tropical surface water. The Ocean Thermal Energy Conversion plant pump a large amount of surface water and deep cold water to run a power cycle and produce electricity.

Optical Fiber Communication

This term is a revolution in the field of telecommunication industry. It allows the telecommunication networks to avail with high bandwidth as well as high-speed data across nations and the globe. It is widely employed for applications starting from telecommunications backbone to the broadband distributions, Ethernet systems and general data networking.


It stands for Radio Detection and Ranging System. This system is based on electromagnetic that is useful to detect the location as well as the distance of the object from the place where the radar is situated. It works by using the radiations into space and supervising the echo or electromagnetic signal from the targeted objects.

Rapid Prototyping

It is the fastest fabrication of physical components, elements or models with the help of 3D computer-aided design (CAD). The formation of model, part or assembly is finished through the use of 3D printing, also known as additive manufacturing. RP is also used in other technologies such as high-speed machining, casting, moulding and extruding.

Space Robotics

It is a kind of development in the general-purpose machines that can survive better in the space environment. These machines are responsible for performing exploration, construction, maintenance, assembly and servicing the tasks that may not be fully understood at the time of designing the robots.

Sensotronic Brake Control

The term is also known as an electro-hydraulic brake which is developed by Mercedes-Benz and Robert Bosch. This system is more precise and faster than the conventional brake system and used an electronic brake system to control for brakes. This brake system is used to pass the commands to the microcomputer as instructed by the driver and further uses the sensor signals to calculate the brake pressure on each wheel.


The device used to convert one type of energy into the other, it is known as Transducer. These devices deal with various types of energies such as mechanical energy, light energy, chemical energy, thermal energy, acoustic energy, electromagnetic energy and many more. For example, mic, fluorescent bulb and speakers.

The term was only thrown around by BMW in press conferences. Valvetronic means Variable intake valve timing system which provides a proper control over variable valve lift from 0.3 to 9.7mm. It is helpful to make improvements in throttle efficiency. It was firstly featured in the production of the car named as 316ti compact.
It is an internal combustion engine or a rotary engine. Instead of reciprocating pistons, it uses the two intertwined rotors. This one is a newly introduced concept in the field of high-efficiency power machine. The design of this machine applied the modified version of thermodynamic otto cycle while using it as an engine.

High Speed Machining (HSM)

This machine was introduced by Carl Saloman in the year 1931. High Speeding Machining has five to ten times the higher speed of cutting as compared to conventional machining and the temperature of the chip tool will start minimizing. It is hard to define this machining as it includes various combinations such as machining at high cutting speed, machining at a high spindle speed, machining at a high feed rate and machining at a high removal rate.

Simputer: The full of simputer is a simple inexpensive mobile computer, which is not costly and it is a handheld computer designed for use in developing nations. It is a device that facilitates image and voice-based interactivity to cope with the problem of poverty and illiteracy. This device can easily be used by anyone and there is no need to take any type of training for operating this device.

Induction Motor

Commonly, it is an AC electric motor and known as an asynchronous motor because their operations work at a speed which is less than synchronous speed. In Induction motor, electric current in the rotor produces a torque which is acquired through electromagnetic induction from the rotational magnetic field under the stator winding.

Power Steering

Since the Wheel, one of the best innovations in the world of vehicles. In simple words, the power steering helps the driver to turn the wheel with ease because of the electric or hydraulic assistance. It works with the help of different mechanical components in synergy and reduces the hassle of the driver as done in the standard steering system.

Friction Stir Welding

It is a procedure of solid-state joining that uses the frictional heat to join the materials generated by a rotating tool or device. This process of joining was developed at TWI Limited in the year 1991 with the help of the non-consumable tool. It is used in industries to join the aluminium alloys of any grade.

Maglev Train

The Maglev train works based on magnetic Levitation and not on the wheels as the conventional trains have. The train gets a bit higher from the tracker because of the electromagnets. Thrust is formed by the electromagnets and it helps the train to move. In comparison with the conventional trains, the marvel train has superb control as there is no dependency on the acceleration and the braking on friction.
