Cardiac Christmas Sock

This image demonstrate an animal ex-vivo experiment which incorporate a three-dimensional electric sock with high-density multiparametric physiological mapping and stimulation functions. The ability to map electrocardiography, temperature, pH, strain and provide optical stimulation is important in clinical cardiology. Elastic silicon membrane is modeled to fit the subject heart shape precisely with the help of 3D printing technology, sensors and stimulators are subsequently transfer-printed on the membrane.
