Abstract: A smart clothes for sensing heart physiological activities and lung respiratory conditions is provided, the smart clothes utilizes conductive connecting elements for being externally connected to a control module, such that the control module can be expanded or upgraded according to functional requirements. Further in the smart clothes, sensing elements and signal transmission wires are made of conductive fabric. As the conductive fabric sensing elements and signal transmission wires are well attached to a clothing body of the smart clothing, the sensing elements can be better adhered to human skin, and thereby sensing accuracy is improved.
