Socat

The U.S. Dept. of Veterans Affairs recently selected Florida State University and HPMI to lead a $4,400,000 project to develop comfortable lightweight, multifunctional sockets for prosthetic limbs. Read the announcement here.

SOCAT

 

  • Developing the next generation above-knee socket systems leveraging innovative materials, advanced manufacturing technology and holistic system approach
  • Enabling more fulfilling lives for amputee patients by providing unprecedented comfort,  functionality, mobility and efficient energy expenditure

KEY CAPABILITIES

  • “On-demand” autonomous volume change management
  • Effective pistoning control
  • Minimal septic skin reactions from wearing the socket for extended periods
  • Intelligent skin temperature control
  • Real-time sensing of socket/liner environment
  • Onboard diagnostics for situation awareness for patient safety and comfort
  • Export of diagnostic data for evidence-driven patient care
 

MILESTONES


The SOCAT team of engineers has produced a light-weight material that autonomously expands and contracts with a patient's limb as it changes in volume throughout the day. This advancement should eliminate the need to continuously add and remove additional socks during the day and provides increased damping and cushioning for additional comfort.

Milestones


THE SOCAT APPROACH

Volume Change Management

  • Real-time  autonomous volume change accommodation with biocompatible auxetic foam  for needed space and comfortable fit
  • Dampening  and cushioning for additional comfort
