The method of claim 1 wherein the analyzing step further comprises synchronizing the first data stream to the second data stream by aligning common-mode events therein. 3. The method of claim 1 wherein the analyzing step is carried out at equipment separate from the first device and separate from the second device, the method further comprising the steps of: communicating the first data stream from the first device to the equipment, andcommunicating the second data stream from the second device to the equipment. 4. The method of claim 1 further characterized in that the first limb is a first arm of the body, and the second limb is a second arm of the body, and wherein the encircling of the first device comprises encircling a wrist of the first limb, and wherein the encircling of the second device comprises encircling a wrist of the second limb. 5. The method of claim 1 wherein the analyzing step comprises detecting at least one of a signal and a communication associated with an ingestible device ingested by the body. 6. The method of claim 1 wherein the first device has a rechargeable energy storage, the method further comprising the step of moving the first limb, and converting movement of the first limb into electrical energy, said electrical energy recharging the rechargeable energy storage. 7. The method of claim 6 further comprising the steps of: inferring a level of physical activity of the body from the converted electrical energy, andcommunicating the inferred level of physical activity external to the first device and external to the second device. 8. The method of claim 1 wherein the measuring of electrical signals at the first device comprises carrying out an analog-to-digital conversion, the first data stream being digital, and wherein the measuring of electrical signals at the second device comprises carrying out an analog-to-digital conversion, the second data stream being digital. 9. The method of claim 8 wherein the analog-to-digital conversions take place with a resolution of at least sixteen bits. 10. The method of claim 1 wherein the analyzing step comprises carrying out an electrocardiogram measurement with respect to a heart of the body. 11. The method of claim 1 further comprising the steps of: emitting first electrical energy within a first band at the first device;detecting the first electrical energy at the second device;emitting second electrical energy within a second band at the first device, the second band different from the first band;detecting the second electrical energy at the second device; andcomparing the detected first electrical energy and the detected second energy with each other, thereby deriving information of interest about the body. 12. The method of claim 11 wherein the step of deriving information of interest about the body comprises inferring a ratio of fluid to non-fluid within the body. 13. The method of claim 11 wherein the step of deriving information of interest about the body comprises inferring blood volume within the body. 14. The method of claim 1 further comprising the step of: communicating the first data stream from the first device to the second device;wherein the analyzing step is carried out within the second device. 15. The method of claim 14 wherein the communicating step is carried out by means of infrared light communications or by means of high frequency radio frequency communications. 16. A system comprising a first device and a second device, the first device comprising a respective electrical signal detector having respective first and second electrodes;the second device comprising a respective electrical signal detector having respective first and second electrodes;the first device shaped for encircling a limb of a subject, the first electrode of the first device disposed to be juxtaposed with said limb when the first device encircles the limb, the second electrode of the first device disposed to be more distant from the limb than the first electrode when the first device encircles the limb;the second device shaped for encircling a limb of a subject, the first electrode of the second device disposed to be juxtaposed with said limb when the second device encircles the limb, the second electrode of the second device disposed to be more distant from the limb than the first electrode when the second device encircles the limb;the electrical signal detector of the first device responsive to signals at the respective first and second electrodes, yielding a first data stream indicative of a difference between the signals at the respective first and second electrodes;the electrical signal detector of the second device responsive to signals at the respective first and second electrodes, yielding a second data stream indicative of a difference between the signals at the respective first and second electrodes;the system further comprising an analysis means, said means responsive to the first data stream and the second data stream, for deriving information of interest about the body. 17. The system of claim 16 where the analysis means is separate from the first device and separate from the second device, the system further comprising: a communications link from the first device to equipment, anda communications link from the second device to the equipment. 18. The system of claim 16 wherein the first device further comprises a rechargeable energy storage, the first device further comprising a means converting movement into electrical energy, said electrical energy recharging the rechargeable energy storage. 19.
