Abstract

The present invention is directed to a wearable system wherein elements of the system, including various sensors adapted to detect biometric and other data and/or to deliver drugs, are positioned proximal to, on the ear or in the ear canal of a person. In embodiments of the invention, elements of the system are positioned on the ear or in the ear canal for extended periods of time. For example, an element of the system may be positioned on the tympanic membrane of a user and left there overnight, for multiple days, months, or years. Because of the position and longevity of the system elements in the ear canal, the present invention has many advantages over prior wearable biometric and drug delivery devices.

First claim

The invention claimed is:

1. A system comprising:
a medial ear canal assembly including a transducer configured to be positioned on a tympanic membrane of a user;
a lateral ear canal assembly including a signal source configured to be positioned in an ear canal of a user; and
sensors connected to the medial ear canal assembly, the sensors being connected to a transmitter, wherein the sensors include sensors adapted to detect biometric data.

2. A system according to claim 1 , wherein the sensors include sensors adapted to detect one or more physical characteristics of the user.

3. A system according to claim 1 , wherein at least one of the sensors comprises a microphone.

4. A system according to claim 3 , wherein the microphone comprises a micro-actuator.

5. A system according to claim 4 , wherein sound received by the micro-actuator is configured to be converted to a back EMF signal.

6. A system according to claim 5 , wherein the system includes a data processor which is configured to convert the back EMF signal to a signal representative of the sound received by the micro-actuator.

7. A system according to claim 6 , wherein the system is configured to transmit the signal representative of the sound received by the micro-actuator to a receiver external to the system.

8. A system according to claim 7 , wherein the receiver comprises a smart phone, a wireless network, or a peripheral device.

9. A system according to claim 1 , wherein at least one of the sensors comprises a skin contacting sensor or a non-skin contacting sensor.

10. A system according to claim 1 , wherein at least one of the sensors comprises an umbo sensor, an eartip sensor, or a tethered sensor.

11. A method of sensing physical characteristics of a system user, the system comprising a medial ear canal assembly configured to be positioned on or near a tympanic membrane of the system user, the medial ear canal assembly comprising transducer sensors and a transmitter, the method comprising the steps of:
using the sensors to measure biometric data of the user;
using the sensors to measure one or more physical characteristics of the user; and
transmitting the measured biometric data using the transmitter.

12. A method according to claim 11 , wherein at least one of the sensors comprises a microphone, and the method further comprising the steps of measuring sound in the user's ear canal.

13. A method according to claim 12 , wherein the microphone comprises a micro-actuator, the method further comprising measuring a back EMF signal.

14. A method according to claim 13 , wherein the system includes a data processor, the method further including the step of converting the back EMF signal to an electrical signal and transmitting the electrical signal to the data signal processor.

15. A method according to claim 14 , wherein the back EMF signal includes a first signal portion representative of the signal received from the system and a second signal representative of at least one physical characteristic of the user, the method further including the step of separating the first signal from the second signal.

16. A method according to claim 14 , wherein the method further includes the step of transmitting the signal to a receiver external to the system.

17. A method according to claim 16 , wherein the receiver comprises a smart phone.

18. A method according to claim 11 , wherein at least one of the sensors comprises a skin contacting sensor or a non-skin contacting sensor.

19. A method according to claim 11 , wherein at least one of the sensors comprises an umbo sensor, an eartip sensor, or a tethered sensor.

20. A method according to claim 11 , wherein the output transducer is used as a sensor.

21. A method according to claim 20 , wherein the sensor is used as a microphone to measure received sound at the tympanic membrane.

22. A method according to claim 21 , wherein the signal from the microphone is coupled to the transmitter.
