Title:
BIOLOGICAL INFORMATION MEASURING DEVICE AND SOUND WAVE COMMUNICATION SYSTEM
Document Type and Number:
Japanese Patent JP2023088708
Kind Code:
A
Abstract:
To suppress an increase in the number of parts for sound wave transmission in a biological information measuring device having a function to transmit acquired biological information as a sound wave.SOLUTION: A biological information measuring device in the present invention includes: a piezoelectric pump 32 capable of supplying fluid for compressing a part to be measured; pressure control units 110 and 320 for controlling pressure for the part to be measured by applying a first driving voltage V1 within a predetermined normal range to the piezoelectric pump 32, and turning on or off a fluid supply operation of the piezoelectric pump 32; biological information measuring units 110, 31, 310, and 311 for acquiring biological information from the part to be measured in a state where the pressure to the part to be measured is controlled; and sound wave communication control units 110 and 320 for executing control to apply a second driving voltage V2 within a predetermined specific range to the piezoelectric pump 32, and cause the piezoelectric pump 32 to generate a sound wave or to stop generating the sound wave.SELECTED DRAWING: Figure 1
