Prosthetic Devices

1
Prosthetic Devices

• Bridging robotics and limb replacement

2
What is a prosthesis?

• Artificial replacement for body part

3
Reasons for prostheses

• Trauma
• Car accident
• War-related accident
• Disease
• Diabetes
• Infection
• Birth defects
• Born without a limb/body part

4
How does your body move?

• Controller
• Brain
• Controls entire body
• Impulses sent from brain to muscles and back to
  brain
• Sensors
• Nerve cells
• Actuator
• Turns impulses from cells into movement
• Muscles

Prosthetic devices use the same principles!
5
How do prosthetic devices work?

• Sensors
• Detects bodys intention
• Biosensors
• Electrodes convert cell impulses into electricity
• Actuators
• Produces mechanical movement
• Motor
• Controller
• Takes information from sensors and sends it to
  actuator

6
What are some problems associated with prosthetic
devices?

• Cost
• Weight
• Durability/strength
• Authentic look

7
How are prosthetics comparable to robotics?

• Robotics
• Prosthetic Limbs
• Biomechatronics
