Shape-Memory-Alloy Actuator Demonstrator
Approx. component budget: Rs. 7,000 - 12,000
Objective
Measure how contraction, force and response time of SMA wire change with current, wire diameter and cooling.
What you will build
Nitinol wire actuators with a bias spring, a controlled current supply (MOSFET with Arduino), and a small gripper or flap mechanism with temperature or position sensing.
Results you can expect
- Strain vs temperature (hysteresis)
- Force vs current
- Response time with and without a fan
- Cycle life estimate
What you will learn
Smart materials, the shape memory effect, actuators and simple control.
Tools and notes
Arduino, MOSFET, thermocouple, Excel. The wire gets hot, so limit the current and time and insulate the mechanism.
Resume points from this project
- Built and tested Shape-Memory-Alloy Actuator Demonstrator; objective: measure how contraction, force and response time of SMA wire change with current, wire diameter and cooling.
- Measured and analysed strain vs temperature (hysteresis) and force vs current; wrote the report and presented the results in a viva. Add your own numbers: [x].
Replace [x] with your own measured results. Write only what you really did.
