Smart Carpet: System and Methods to Automatically Recognize and Track Physical and Physiological Activities for Healthcare

Case ID:

This technology is a carpet with various sensors embedded within it to monitor and track a patient's movement. The carpet provides information regarding frailty, risk of falling, outcomes of rehabilitation, effects of plantar wound healing, and emergencies such as sudden falling due to heart attack.


The U.S. is expected to have more than 20% of the population over the age of 65 by 2029. With an aging population, there is a greater need for preventative, acute, rehabilitative, and long-term health care services for senior citizens. Although movement-monitoring devices exist in the market, they are unable to provide clinically meaningful information at the hefty price a patient pays to install these devices in their homes.



  • Commercial healthcare
  • At-home healthcare


  • Non-invasive monitoring technology
  • Operates continuously without patients changing their normal routine
  • Provides detailed information about gait and motor performance during locomotion, sitting, and standing
  • Collects other information such as respiration rate, heart rate, and heart variability by assessing fluctuation in plantar pressure of person
  • Flexible material adapts to stairs, a common location for home-related accidents to occur
  • Cost effective materials reduce costs to cover large areas of a patient's home

Status: issued U.S. patents #10,478,126 and #10,856,810
