Overview

Analysis shows auxetic structures enhance pressure distribution in mattresses, suggesting improved outcomes for pressure ulcer prevention.

Key Points

  • Designed auxetic structure achieved compressive stress of 7 to 8 kPa at 40% compression, enhancing support.
  • Fatigue tests revealed resilience of the structure is influenced by strain, highlighting its durability over time.
  • Finite element method was used for the numerical design of auxetic structures, ensuring precise mechanical property control.
  • Results support the use of tailored auxetic structures in creating mattresses designed for the biomechanical needs of patients.
