Objective

The objective of this lab is to analyze and understand the biomechanics involved in human gait, the mechanical properties of biomaterials, and the principles of biomedical device design. This report will detail the procedures, observations, and findings of the experiments conducted in the lab.

Materials and Methods

Materials

  • Human gait analysis system

  • Force plates

  • Biomaterial samples (hydrogen, Titanium alloy, Polycarbonate)

  • Biomedical device prototypes

  • Computers with analytical software

  • Measuring instruments (calipers, micrometers)

Methods

Human Gait Analysis

To analyze the human gait, volunteers were asked to walk across a predefined path fitted with force plates. The gait analysis system recorded parameters, including:

  • Stride length

  • Walking speed

  • Ground reaction forces

  • Joint angles

Biomechanical Properties of Biomaterials

The mechanical properties of different biomaterials were tested using tensile and compressive tests. The following properties were measured:

  • Tensile strength

  • Compressive strength

  • Young's modulus

  • Elongation at break

Biomedical Device Design

Various biomedical device prototypes were evaluated for their functionality, safety, and usability. The design evaluation included:

  • Prosthetic limb prototypes

  • Implantable devices

  • Diagnostic tools

Discussion

Human gait analysis shows average stride length and walking speed are normal, with ground reaction forces and joint angles usable for improving ergonomic footwear and prosthetics. Biomechanical tests found titanium alloy ideal for load-bearing implants due to its strength; hydrogel is suitable for soft tissue; and polycarbonate offers a strength-flexibility balance. Biomedical device evaluation highlights that while prototypes score high on functionality and safety, usability needs enhancement for better patient and provider use.

Conclusion

In summary, this lab successfully analyzed key aspects of human biomechanics, characterized the mechanical properties of various biomaterials, and evaluated the design of biomedical devices. These findings are expected to contribute to the ongoing development and improvement of medical engineering solutions.
