This article describes an extracorporeal sensing system composed of a lightweight, highly sensitive printed accelerometer, which is integrated with the readout circuit. The bandage-type accelerometer system is attached to various positions of human body conformally to obtain vital signals such as pulses and heart rate, as well as motion detection. Moreover, when the sensor is attached to the chest near the heart, broad respiratory rate can also be measured. Both human pulse and motion are essential indicators of health conditions. This bandage-type attachable sensor system allows continuous detection of various biosignals as long-term medical diagnostics for patients' convenience.
