Title:
生体内情報伝達システムおよび送信装置
Document Type and Number:
Japanese Patent JP6832218
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To reduce instability due to environmental variation and thereby perform in-vivo information transmission stably with high quality.SOLUTION: A signal generation unit 11 generates a signal wave by modulating a carrier wave on the basis of communication data to be transmitted, a sound wave excitation unit 12 excites a sound wave for a human body 100 on the basis of the signal wave generated by the signal generation unit 11, an acoustic sensor 21 receives the sound wave from the human body 100, and a signal processing unit 22 demodulates the communication data from the received sound wave. This reduces instability due to environmental variation and can perform in-vivo information transmission stably with high quality.SELECTED DRAWING: Figure 1
