Abstract
A miniature wireless apparatus for collecting physiological signals comprises an electrode pair, an amplifier module, a microcontroller, a wireless module, and a battery. The electrode pair collects a pair of physiological signals of a person under test. The amplifier module amplifies the pair of physiological signals. The microcontroller performs an analog-to-digital conversion and a data compression for an amplified physiological signal generated by the amplifier module. The wireless module modulates a digital physiological signal generated by the microcontroller and transmitting the modulated digital physiological signal to a receiver at the far end. The apparatus can be implemented by a structure of multilayered circuit boards. With the progress of semiconductor technology, all the components of the miniature wireless apparatus can be further integrated to one circuit board, or even one chip.
