Method & Evidence

AimTo develop and validate an open-source, wireless vest for accurately measuring autonomic functions (cardiac activity, respiration, movement) in infants aged 8-24 months.
MethodExperimental validation
ProcedureThe study involved designing and constructing an open-source, wireless vest. The vest's validity was assessed by (1) demonstrating known clinical landmarks of a heartbeat, (2) observing an infant in a period of sustained attention, and (3) correlating accelerometer data with observed infant behaviors.
ContextInfant developmental research, wearable technology
