Agitator to stimulate the central nervous system
A tactile and audible sensation can be provided to a patient using a coiled or scrolled film in response to a received control signal. The tactile and audible sensation can be configured to stimulate the patient's central nervous system to sufficiently interrupt and undesirable sleep behavior of the patient, but avoid significantly changing a sleep state of the patient.
1. A method for stimulating a central nervous system of a patient suffering from a sleep disorder, comprising:
receiving a control signal from a controller;
transferring a mechanical vibration of a coiled or scrolled film to a housing, sized and shaped to fit within, on, around, or behind an ear of the patient, in response to the received control signal, wherein the housing includes the coiled or scrolled film; and
passing a tactile and audible sensation to the patient using the housing, the tactile and audible sensation configured to stimulate the patient's central nervous system to interrupt an undesirable sleep behavior of the patient, but avoid changing a sleep state of the patient.
2. The method of claim 1 , including:
receiving sleep information from a patient, the sleep information including at least one of:
respiration information of the patient from a respiration sensor; or
information indicative of a sleep state of the patient from a sleep state sensor; and
producing the control signal using the received sleep information.
3. The method of claim 2 , wherein the receiving the sleep information from the patient includes receiving the respiration information of the patient from the respiration sensor.
4. The method of claim 1 , wherein the transferring a mechanical vibration of the coiled or scrolled film includes using a metalized polyvinylidene fluoride (PVDF) film having at least one of a series or parallel bimorphic structure.
5. The method of claim 1 , including producing an alternating current (AC) excitation voltage control signal to control expansion and contraction of the coiled or scrolled film according to an instantaneous voltage polarity of the control signal.
6. The method of claim 5 , wherein the producing the AC excitation voltage control signal includes producing the AC excitation voltage control signal at a frequency configured to match a resonant frequency of the coiled or scrolled film to provide a desired efficiency of the provided tactile and audible sensation.
7. The method of claim 1 , wherein the film includes a coiled or scrolled polyvinylidene fluoride (PVDF) film.
8. The method of claim 7 , wherein the PVDF film includes a metalized PVDF film having at least one of a series or parallel bimorphic structure.
9. The method of claim 1 , wherein the film includes a coiled film.
10. The method of claim 1 , wherein the film includes a scrolled film.
11. The method of claim 1 , wherein the housing is sized and shaped to fit within the ear.
