From: A novel automatic cough frequency monitoring system combining a triaxial accelerometer and a stretchable strain sensor

Figure 1

Devices for cough frequency monitoring system in this study. (A) Triaxial accelerometer (WHS-3 SENSOR). (B–D) Stretchable strain sensor (C-STRETCH). There is a sensor in the red square (B). This sensor is soft and can be easily stretched (C,D). (E) Strain sensor, cable, and transmitter. (F) The triaxial accelerometer was attached to the epigastric region. A stretchable strain sensor was worn around the participant’s neck.
