The invention discloses a dual-mode
electrophysiology acquisition
system and method for a multi-mode fingertip monitor, and belongs to the technical field of
medical electronics and biological
signal measurement. The
system is integrated in fingerstall type wearable equipment supporting double working
modes of high-fidelity recording and
continuous monitoring, and is characterized by comprising at least two electrodes in contact with the
skin; the high-precision bioelectricity analog front-end
chip conforms to the medical standard; a low
power consumption bioelectricity monitoring unit; and the channel switching circuit is controlled by the main controller. The high-precision analog front-end
chip is configured to switch or perform
time division multiplexing on at least one
signal input channel between a first configuration for collecting electrocardiogram signals and a second configuration for collecting
skin electrical activity signals by dynamically reconfiguring an internal register of the high-precision analog front-end
chip; therefore, hardware-level synchronous acquisition of two kinds of bio-
electricity signals in a high-fidelity recording mode is realized, and sampling of the two kinds of bio-
electricity signals is based on the same main
clock source. Through the architecture of dual-core isomerism, mode driving and hardware dynamic
multiplexing, the contradiction between medical-level precision electrocardio /
skin electricity synchronous acquisition and ultra-long endurance
continuous monitoring which are simultaneously realized in micro fingerstall equipment is solved.
