YARN TYPE PIEZOELECTRIC NANOCOMPOSITE BREATH SENSOR COMPRISING OF THE SAME AND PREPARATION METHOD OF THE YARN TYPE PIEZOELECTRIC NANOCOMPOSITE

摘要

The present invention relates to a fibrous piezoelectric nanocomposite, a respiratory monitoring sensor including the same, and a manufacturing method of the fibrous piezoelectric nanocomposite. By using the fibrous piezoelectric nanocomposite and the like, a nanogenerator, a self-powered respiratory monitoring sensor, and the like with excellent sensitivity, repeatability, stability, etc. are capable of being provided. The fibrous piezoelectric nanocomposite and the like include: a first electrode which is an electrically conductive flexible fiber; a first piezoelectric active layer located on the first electrode and containing bismuth titanate; a second piezoelectric active layer located on the first piezoelectric active layer and having piezoelectric activity and insulating properties; and a second electrode layer located on the second piezoelectric active layer and containing electrically conductive metal.
