Title: Sensor Interface for Preventing Tissue Damage


Invention: Inventors at the University of Arizona have developed a sensor interface designed to detect and prevent tissue damage. The device is attached to the subject’s skin, senses and identifies regions within the skin-contact surface at risk for damage from these stressors, and then makes adjustments to those regions in order to prevent tissue damage.


Background: Tissue damage can result from prolonged exposure to a variety of stressors including pressure, moisture, shear, temperature, pH levels and other factors. A number of topical treatments are used to care for skin damage, but only once the damage has been done. As a means of detecting and preventing tissue damage, Dr. Marvin Slepian has developed a technology that is capable of sensing potential risk for damage via attachment the user. 



  • Hospital beds and patients prone to bed sores
  • Maintaining temperature via blankets, clothing, etc.
  • Athletic clothing and/or equipment
  • Compression equipment for diabetics



  • Capable of detecting stressors that may be damaging to tissues, which prompts a response in order to alleviate them
  • Could help patients with reduced sensation or who have difficulty moving who may be more prone to bedsores or other morbidities
  • Provides a safer and less labor-intensive alternative
  • Capable of taking readings over specific areas of the skin that are most at risk for damage due to certain stressors
  • Stressors can be responded to in a more precise way than would be possible without the sensors
  • Capable of being programmed and then providing data feedback
  • Able to interact with computer systems, including electronic medical records
  • Potential to allow data gathered by the sensor system to be used to fine-tune specific treatments for each patient
