The invention discloses an IPMC-based self-adjusting nasal
dilator which comprises a breathable layer, a transverse driving part, a longitudinal driving part, at least one sensing IPMC, a battery and a controller, and the transverse driving part, the longitudinal driving part, the at least one sensing IPMC, the battery and the controller are arranged in the breathable layer, and the breathable layer comprises a transverse section and at least one longitudinal section fixedly connected with the transverse section. According to the
dilator, through the structural arrangement of the transverse section and the longitudinal section, the
dilator is of a U-shaped structure, the transverse driving part and the longitudinal driving part are arranged in the transverse section and the longitudinal section correspondingly, transverse dilation and longitudinal dilation on the two sides of a nasal channel can be achieved, an elastic layer is replaced with the IPMC, and force almost perpendicular to the nasal channel is generated by driving the IPMC; the sensing IPMC can increase the expansion of the
nasal passage, the sensing IPMC can monitor the expansion degree of the
nasal passage of a user in real time, sensing current is transmitted to the controller to enable the expansion force to be always kept in a comfortable range, and meanwhile, the IPMC can generate
specific heat during working to relieve nasal obstruction.
