a power module including a battery for storing energy; and

a control module to communicate information and receive operational commands,

wherein said control module includes an indicator which communicates to a user whether a current position of said sensor module on a patient'"'"'s body is sufficient to enable communication of an adequate data signal from said sensor module.

2. The wireless electronic stethoscope device of claim 1, wherein said sensor module includes a contact microphone, piezoelectric microphone, micro-electrical mechanical system microphone, electromagnetic microphone, or semiconductor process microphone.

3. The wireless electronic stethoscope device of claim 1, wherein said processor module performs analog to digital electrical signal conversion, frequency range electrical signal filtering, or other digital signal processing operations on data provided by said sensor module.

4. The wireless electronic stethoscope device of claim 1, wherein said control module comprises a plurality of buttons, switches, indicator lights, or other control interfaces.

5. The wireless electronic stethoscope device of claim 1, wherein said control module includes a touch-sensitive display screen that also functions as a control mechanism to receive operational commands.

6. The wireless electronic stethoscope device of claim 1, further comprising:

a detachable bell module, which, upon attachment to said main body, is disposed contiguous with said sensor module.

7. The wireless electronic stethoscope device of claim 1, further comprising:

a wireless receiver, comprising;

a processor module to coordinate operation of the wireless receiver modules;

a wireless communication module to transmit data to, and receive data from, the wireless communication module of the pen-shaped main body;

a power module including a battery for storing energy;

a control module to communicate information and receive operational commands; and

an audio module that transmits an audio signal to an electronic speaker or to an electronic audio output jack.

8. The wireless electronic stethoscope device of claim 7, wherein said communication module of the pen-shaped main body can transmit and receive data to a plurality of wireless receivers.

9. The wireless electronic stethoscope device of claim 8, wherein said control module of the pen-shaped main body enables the transmission of data to said plurality of wireless receivers using a single button.

10. The wireless electronic stethoscope device of claim 1, wherein said wireless communication module of the pen-shaped main body supports an electronic network data communication protocol.

11. The wireless electronic stethoscope device of claim 10, further comprising a computer supporting communication via said electronic network data communication protocol.

12. The wireless electronic stethoscope device of claim 11, wherein said computer performs computational analysis of data received from said wireless communication module of the pen-shaped main body via said electronic network data communication protocol.

13. The wireless electronic stethoscope device of claim 4, wherein:

the plurality of buttons includes a plurality of audio frequency buttons, each audio frequency button enabling amplification of a predetermined frequency range, and

the predetermined frequency ranges associated with the plurality audio frequency buttons are different from one another.

14. The wireless electronic stethoscope device of claim 4, wherein:

the plurality of buttons includes a master button that is configured to set the wireless electronic stethoscope as a master device, and

the master device transmits the digital and analog data to another wireless electronic stethoscope device.

15. The wireless electronic stethoscope device of claim 1, wherein:

upon the sensor module detecting a physiological anomaly, the processor module generates a health report indicating the physiological anomaly and transmits the health report to a receiver, and

the health report comprises at least one selected from a group consisting of;

a heart rate and a respiratory rate.

16. A method of detecting and transmitting body sounds wirelessly, comprising the steps of:

determining that a current position of a detached wireless electronic stethoscope on a patient'"'"'s body is sufficient to enable communication of an adequate data signal from said the detached wireless electronic stethoscope;

detecting body sounds through the detached wireless electronic stethoscope; and

transmitting said body sounds simultaneously to one or more receivers, wherein;

said body sounds can be stored and retrieved by one or more receivers;

or

said body sounds can be analyzed for screening or diagnostic purposes.

17. The method of claim 16, wherein:

said screening or diagnosis is conducted in a separate location from said detached wireless electronic stethoscope.

18. The method of claim 17, wherein:

said screening or diagnosis is conducted through the use of cloud computing.

19. A method of detecting and transmitting body sounds wirelessly, comprising the steps of:

determining that a current position of the detached wireless electronic stethoscope on a patient'"'"'s body is sufficient to enable communication of an adequate data signal from the detached wireless electronic stethoscope;

detecting body sounds through the detached wireless electronic stethoscope; and

transmitting said body sounds simultaneously to one or more mobile computing devices.

20. The method of claim 19, wherein:

said body sounds can be stored and retrieved by one or more desktop or mobile computing devices;

or

said body sounds can be analyzed for screening or diagnostic purposes.

21. The method of claim 20, wherein:

said screening or diagnosis is conducted in a separate location from said detached wireless electronic stethoscope.

22. The method of claim 21, wherein:

said screening or diagnosis is conducted through the use of cloud computing.

23. The method of claim 20, wherein:

said screening or diagnosis is performed by an automated expert-system.

24. The method of claim 20 wherein:

said screening or diagnosis is performed for population-level analysis.

25. A system comprising:

a master wireless electronic stethoscope; and

a plurality of slave wireless electronic stethoscopes,

wherein the master wireless electronic stethoscope is configured to detect a physiological sign of a patient and transmit the physiological sign to each of the plurality of slave wireless electronic stethoscopes,

wherein each of the plurality of slave wireless electronic stethoscopes is configured to store and playback the physiological sign, and

wherein the physiological sign is at least one selected from a group consisting of;

respiratory rate and heart rate.
