AIST:highly accurate electrocardiogram measurement: the thinnest､ lightest biological circuit
Research achievement points:
Developed the world’s thinnest and lightest biological signal amplification circuit and demonstrated highly accurate electrocardiogram measurement with less noise.
A thin and soft organic circuit realizes differential amplification that can accurately measure weak signals from living bodies without wearing them.
Equipped with a function that can remove disturbance noise such as walking, it will be possible to easily and accurately measure living bodies in the future.
Create new value such as advanced biometrics at home.
Conventional biometric circuit:
Until now, biological measurement circuits for medical applications have been composed of hard electronic elements such as silicon transistors.
However, if an electronic device touches soft biological tissue, it tends to cause inflammation, making it difficult to measure biological signals for a long time.
This biological measurement circuit:
In daily life, not only ECG signals but also various weak biological signals (such as brain waves and fetal ECGs) can be accurately captured.
Accurate monitoring is possible without a feeling of equipment wearing.
The results of this research will be published in the British scientific journal “Nature Electronics” (online) on Friday, August 16, 2019 at midnight.
