In an effort co-led by Lt. Rachel Shveda, MS and Anoop Rajappan, PhD, researchers from the Preston Innovation Laboratory have demonstrated a wearable energy-harvesting device made from textiles. The device is worn comfortably around the waist of a user and accumulates air pressure as the user walks. The pressurized gas can then be used to power other wearable pneumatic devices on the user. Science Advances published the article [PDF], and a press release about the device can be found here.
