Adherence may be a factor limiting wearable biosensors application and use of to collect large amounts of data.
However, it is often poorly studied.
In our experience within and beyond ALAMEDA project, user’s engagement (including interaction on the patient-researcher axis, information, training and supervision) is pivotal to maximise compliance and overall adherence.
