BIO-SIGNAL MEASURING DEVICE
FIG14 is a schematic diagram showing a fourth embodiment of the bio-signal measuring device according to the present invention  FIG15 is a schematic diagram showing a fifth embodiment of the bio-signal measuring device according to the present invention
The MPU 25 performs advanced processing that cannot be performed in an MCU 121 (refer to FIG14) in the bio-signal measuring instrument 1 having a restriction in the power source. The MPU 25 performs, for example, encryption processing or anonymization processing in which an individual cannot be identified, from the viewpoint of personal information protection. The memory 26 temporarily stores the accumulation of past data, case data on the cloud, or the like. Next, a fourth embodiment of the bio-signal measuring device will be described with reference to FIG14. In the fourth embodiment, the bio-signal measuring instrument 1 has a communication function with the power feeder 2.  As another embodiment (a fifth embodiment of the present invention) of the communication function with the power feeder 2, as shown in FIG15, an aspect including a wakeup circuit 131 as connection detection means, a switch (SW) 132 for modulation, an ADC 133, an error correction decoding circuit 134a, an error correction coding circuit 134b, and a communication control unit 135 is also included in the present invention.
