Try these first

  1. 1.

    What does piezoelectricity refer to?

    Hint

    Think about how materials respond to an electrical charge.

  2. 2.

    Name one common material used in piezoelectric actuators.

    Hint

    It has specific properties that make it effective.

  3. 3.

    What property allows piezoelectric actuators to generate movement?

    • Magnetism
    • Piezoelectricity
    • Thermal expansion
    Hint

    Think about how certain materials respond to electricity.

  4. 4.

    True or False: Piezoelectric actuators can provide large movements.

    • True
    • False
    Hint

    Consider the size of the adjustments they can make.

  5. 5.

    Design a micro-positioning system using piezoelectric actuators for a laser alignment task. Consider the specifications for precision.

    Hint

    Think about how many degrees of freedom you will need.

  6. 6.

    Evaluate the trade-offs between piezoelectric actuators and traditional electric motors for a robotics application requiring speed and precision.

    Hint

    Consider the application context and what is more critical—small movements or stronger force.
