Nitinol Engine

Made in India – Nitinol Heat Engine Model

Thermomechanical STEM Learning Device for Science Projects and Demonstrations

Presenting an innovative and educational model proudly made in India – the Nitinol Heat Engine by Crekart. This thermo-mechanical engine demonstrates the fascinating behavior of shape memory alloys, specifically Nitinol (Nickel-Titanium alloy), which changes shape when heated and returns to its original form upon cooling.

This device works by converting heat energy into mechanical motion through the contraction and expansion of the Nitinol wire. As the wire heats up, it contracts and pulls the large wheel into rotation. Once it cools down, it relaxes back to its original length, repeating the cycle continuously.

This model is a perfect demonstration tool for science students, educators, and innovators who want to explore the principles of thermodynamics, energy transformation, and smart materials.

Working Principle:

When heat is applied to the Nitinol wire, it contracts due to its shape memory property. This contraction pulls the large wheel, causing it to rotate. As the wire cools, it returns to its original shape, allowing the cycle to repeat and maintain continuous motion. This simple yet powerful demonstration showcases how thermal energy can be transformed into mechanical energy without the need for motors or batteries.
