Review Questions

• How does the application of force impact the functionality of prosthetic limbs?
  • The application of force is fundamental for the functionality of prosthetic limbs, as it enables users to move and control their devices effectively. When a user exerts force through muscle contractions or neural commands, it is translated into movement by the prosthetic's actuators. This interaction allows for tasks like grasping objects or walking, making the experience more natural and intuitive for the user.
• What role do sensors play in measuring force for controlling prosthetic limbs?
  • Sensors are crucial in measuring force because they detect the user's intentions and the amount of force being applied. These measurements help the prosthetic limb respond accurately to the user's movements, allowing for precise control. By providing real-time feedback on force exertion, sensors enable a more seamless integration between the user and their prosthetic device, enhancing overall functionality and usability.
• Evaluate how advancements in technology are changing the way force is applied and controlled in prosthetic limb design.
  • Advancements in technology are significantly transforming how force is applied and controlled in prosthetic limb design. Innovations such as brain-computer interfaces enable direct translation of neural signals into movement commands, which enhances user control over their devices.
