Description

technical field [0001] The invention relates to the field of flexible electronics, in particular to a breathable and stretchable conductive yarn and a preparation method and application thereof. Background technique [0002] Stretchable electronics are critical for practical wearable applications ranging from personal healthcare, human activity monitoring to human-machine interfaces. Conventional stretchable electronic devices mostly use low-permeability elastomer (usually silicone rubber) films as substrates, which makes the high air permeability for wearable applications unsatisfactory. Compared with film-based devices, fiber-based devices are softer, lighter, and more conformable to the body's curvilinear surface, and can be easily integrated into a variety of textiles without compromising the breathability and physical comfort of the substrate. On the other hand, the fiber structure is an ideal form for transmitting power and signals. When used as a sensor, distributed ...
