By using this product a sports bra manufacturer or retail store can fit their customers with a bra that reduces excess breast motion during exercise, thereby making their customers more comfortable during any physical exertion.


Wearable technology in the fitness industry has witnessed a surge in the past decade. There are numerous smart textiles which measure the heart rate and breathing rate, but none deal with measuring soft tissue movement. The movement of soft tissue  is particularly important for women in order to minimize breast movement, which is uncomfortable for some women during physical exertion, particularly running. Researchers at the University of Delaware have developed a smart bra that allows the measurement of breast motion during running.  By using this tool, a bra can be fit and adjusted so motion is minimized, and the runner is therefore more comfortable during exercise.


  • Instantaneous measurement and feedback
  • Comfortable and easy-to-wear
  • Personalized workout tool


Researchers at the University of Delaware have developed a novel system of wearable sensors that they have applied to a women’s bra. These sensors measure soft tissue acceleration of the breasts in real time. Three sensors are strategically, and comfortably placed in easy to wear clothing, and interfaced to a device to provide feedback to either the user, or the sales person during bra fitting.  The result provides a more comfortable bra, a better exercise experience, and can even be used to modify exercise behavior, for example gait during running. 


A prototype is being tested and currently is being optimized for comfort, appropriate feedback and interface design.
