Menopausal women who are suffering from hot flushes may no longer need to reach for the pills in the future. Ir. Geertje Hofstee graduated from the Faculty of Industrial Design Engineering on 5 September with her design for a body-cooling jacket that can automatically detect a hot flush on the skin and will respond by activating cooling elements integrated within the clothing. ‘During a hot flush, the skin temperature can rise by between 1 and 7 degrees, so it is quite easy to detect,’ explains Hofstee. The cooling effect is achieved by what are known as Peltier elements. These convert an electric current into a temperature difference between two different metals. As a result, one side of the element (which is almost touching the skin) activates the cooling mechanism.
