Many parts of human body generate internal sound during biological processes,
which are rich sources of information for understanding health and wellbeing.
Despite a long history of development and usage of stethoscopes, there is still
a lack of proper tools for recording internal body sound together with
complementary sensors for long term monitoring. In this paper, we show our
development of a wearable electronic stethoscope, coined Patchkeeper (PK), that
can be used for internal body sound recording over long periods of time.
Patchkeeper also integrates several state-of-the-art biological sensors,
including electrocardiogram (ECG), photoplethysmography (PPG), and inertial
measurement unit (IMU) sensors. As a wearable device, Patchkeeper can be placed
on various parts of the body to collect sound from particular organs, including
heart, lung, stomach, and joints etc. We show in this paper that several vital
signals can be recorded simultaneously with high quality. As Patchkeeper can be
operated directly by the user, e.g. without involving health care
professionals, we believe it could be a useful tool for telemedicine and remote
diagnostics.
