New 3D printed fall-impact protection pads offer enhanced safety for the elderly. Utilizing 3D body scan data, these custom-fit pads significantly reduce impact forces during falls.

Area of Science:

  • Biomedical Engineering
  • Materials Science
  • Gerontology

Background:

  • Falls pose a significant health risk for the elderly, necessitating effective protective measures.
  • Existing fall-impact protection often compromises comfort, aesthetics, or fit.
  • Three-dimensional (3D) printing offers potential for personalized protective gear.

Purpose of the Study:

  • To develop customized fall-impact protection pads for the elderly using 3D printing.
  • To create pads that are highly suited to individual human body shapes.
  • To verify the impact protection performance of 3D printed curved pads.

Main Methods:

  • Utilizing 3D human body scan data to generate personalized pad surfaces.
  • Developing a 3D modeling process for curved protective pads with hexagonal mesh and spacer fabric structures.
