This mitten lights up when its wearer shakes hands with someone. It has two exposed soft contacts around the thumb and across the palm which, when bridged by bare skin, turn on the LED embedded on the flower. The mitten itself was created by fashion designer Isabel Tomás, and we then sewed a simple touch switch circuit onto it using conductive fabric and thread. It also works with high fives and holding hands 🙂
Isabel and I designed this as a soft circuits exercise for some upcoming materials workshops. You can find all the instructions and images we prepared for this purpose @ openMaterials:
