A Study on a Carbon Fabric Warmer for Antimicrobial Use on the Plantar Skin

Key Points

• The research aims to develop and assess a carbon fiber warmer for antimicrobial use on the plantar skin.
• Developed an antimicrobial carbon fabric warmer using rayon carbon fibers carbonized at 3,000 °C.
• Evaluated electrical and thermal properties including temperature response and heat generation efficiency.
• Conducted antibacterial tests against Staphylococcus aureus and Klebsiella pneumoniae.
• Assessed heat generation capability at low power consumption.
• Achieved rapid temperature rise with stable control above 35 °C and high heat generation efficiency.
• Reduced bacterial count to 20 CFU/mL or less after 18 hours, demonstrating a 99.9% reduction rate.
• Proved effective antimicrobial properties due to the material's conductive and chemical stability.
