Wearable device and system for a tamper free electric stimulation of a body

A wearable device (100) for electric stimulation of a user's body, wherein the wearable device (100) is adapted to fit a portion of the user's body, the wearable device (100) comprising at least one electrode (104a-d) embedded in the wearable device (100) for transferring a stimulating current to the user's body; a connection point (106) being an intermediate connection between the at least one electrode (104a-d) and a control unit (110), the control unit (110) being adapted to generate the stimulating current; and means for detecting if a change in a physical relationship between the connection point (106) and the at least one electrode (104a-d) exceeds a predetermined threshold value, thereby enabling detection of misuse and tampering with the device (100). This ensures no harm is done to the user, for example, by placing the electrodes in such a way that a risk of stimulating the heart exists which may lead to a heart failure. Furthermore, tampering with the device can be detected,thereby enabling an anti-
