Abstract
The present disclosure relates to a wearable motion detection device (12) configured for detecting body-to-ground proximity, and to a related method. The motion detection device (12) comprising a capacitance detection unit (70) arranged to detect body-to-ground capacitance, the capacitance detection unit (70) comprising a first electrode (30) arranged to contact a body portion (16) of a monitored subject, when the device (12) is worn, a second electrode (32) that is arranged separately from but operatively connected with the first electrode (30), a shield electrode (34) that is arranged to shield the second electrode (32) from the first electrode (30), the device (12) further comprising a control unit (74) arranged to determine, under consideration of a body-to-ground capacitance signal provided by the capacitance detection unit (70), whether a fall event occurs. The present disclosure further relates to a corresponding computer program for implementing a motion detection method.
