Vigour, by Pauline van Dongen, is a sensor sweater developed for geriatric rehabilitation. The knitted cardigan, with integrated stretch sensors, discreetly and continuously monitors upper body movement. Two sensors monitor lower back movement, and one under each arm monitors shoulder and arm movement. Data is transferred to the user, caregiver, or physician. It can be worn all day, during normal activity, rest, and exercise. Its app provides visual and auditory feedback, in real time, to inform and motivate the user.
