Healthcare. There is also a vast body of literature on healthcare applications of wearable sensing [112]. A seminal research
contribution is the AMON system [113], a wrist-worn medical monitoring and alert system that offers the continuous
collection of multiple vital signs (blood pressure, pulse oximeter oxygen saturation, EKG) as well as accelerometer data
for medical emergency detection. Another key contribution is Harvard’s CodeBlue system [114], a wireless infrastructure
for emergency medical care where wireless vital sign sensors report to higher-end devices. A comprehensive survey of
healthcare applications of wearable sensing can be found in [115]. A recent survey specific to applications to rehabilitation
can be found in [116]. In the remainder of this section, we will focus on recent commercial development that is unfolding
at the time of writing.
