Abstract
A wearable electronic device comprises a base for mounting a plurality of sensors, where the sensors acquiring physiological data of a user wearing the device. By providing multiple sensors on a single device, additional physiological data, such as pulse transit time, can be provided. To ensure quality data is collected, the device includes a spring mechanism for applying a compressive force on the sensor to force it into the skin of a user.
