The present invention relates to a linear piezoelectric device having flexibility, and more specifically, to a linear piezoelectric device having flexibility, which is easily arranged, used, and treated, and also can be compatibly used for various usages since the linear piezoelectric device is formed in a linear structure having flexibility. According to the present invention, the linear piezoelectric device having flexibility comprises: a dielectric member including a ferroelectric polymer; and an electrode member disposed to be electrically connected to the dielectric member. The dielectric member and the electrode member are linearly disposed together in a longitudinal direction, and the dielectric member and the electrode member are intertwined or wound with each other. Accordingly, the linear piezoelectric device having flexibility of the present invention is formed to be a linear structure, and to allow the electrode member and the dielectric member to have flexibility, and has elasticity which is contracted and expanded when an external force is applied, thereby being variously used as not only a generator but also a pressure sensor (a liner sensor which outputs an electric signal corresponding to the application of the external force) installed in a thin planar object which is used as a material of a product such as clothing, bedding, etc. Furthermore, according to the present invention, the linear piezoelectric device having flexibility has a support line or an outer layer with yarn fibers, the entire diameter is formed to be less than or equal to 1,000 μm so as to provide a fiber-like soft tactility, and can be freely bent so as to arrange or weave the same on fabric in a way of embroidery, so an installation, treatment, and usage thereof is easy. |
