<P>PROBLEM TO BE SOLVED: To increase the measuring precision by improving the SN ratio of bio-information in an apparatus which measures the bio-information such as an electrocardiac waveform by using electrode sections which are installed on the right and the left of a steering wheel. <P>SOLUTION: Two kinds of devices are applied to the electrode sections 10 and 20 which are installed on gripping sections on the right and the left of the steering wheel 2. (1) The device regarding material: The material is made to dent by gripping force imparted when a driver grips the steering wheel 2. Compared with the case of a material which does not dent, a large number of recess sections are formed just like dimples of a golf ball on the surfaces of respective electrode sections 10 and 20 when the driver grips the steering wheel 2, and thus, the surfaces of the electrode sections 10 and 20 are constituted to be uneven. The unevenness expands "the contact areas between the electrodes and the skin of the driver" when the driver grips the steering wheel 2 compared with a case without such a constitution. <P>COPYRIGHT: (C)2009,JPO&INPIT |
