It's summer in Japan and, like humans, the cows are feeling the heat.
Called Ushi-ble, the shirt is made of a "feel-cool" material often found in sportswear. The shirt, which covers the cow's neck and shoulders, has a sensor installed that monitors the dampness of the material. When it becomes too dry, water is pumped through a tube so the cow is drenched. It vaporises later to bring the cow's temperature down by approximately five degrees.
Tests done by Gunze and the Kyoto Prefectural Agriculture, Forestry and Fisheries Technology Center have proven Ushi-ble effective in minimising the consequences of heat stress in cows. For example, while milk production usually falls by around 10 percent during summer, a reduction in the decline is observed in cows donning the shirt.
Tech wearables aren't just for cattle. In 2015, apparel company Lukla Endeavour developed a jacket that comes with aerogel insulation -- a NASA technology -- that keeps its wearers warm in cold climates. The following year, Singapore startup, Tware, designed a massage jacket that pounds its wearer's back on the go.
