A facepiece respirator configured to be worn by a user, the facepiece respirator comprising:
- a first layer being positionable adjacent the user;
- a second layer coupled to the first layer;
- and
- a filtering layer positioned between the first layer and the second layer, the filtering layer including a piezoelectric film.
A facepiece respirator configured to be worn by a user, the facepiece respirator comprising:
- a first layer positionable adjacent the user;
- a second layer coupled to the first layer;
- and
- a filtering layer positioned between the first layer and the second layer, the filtering layer including an electrospun piezoelectric film,
- wherein each of the first layer, the second layer, and the filtering layer comprise a sterilizable and biodegradable material.
A method of manufacturing a facepiece respirator, the method comprising:
- forming a piezoelectric film by electrospinning a first material solution dissolved in a solvent to form a nanofiber mat;
- applying heat to the nanofiber mat;
- and
- positioning the piezoelectric film between a first layer and a second layer, the first layer being positionable adjacent to a user.
