摘要：
Disclosed is a sensor device configured to process stretch data for determining a stretch value of a body part. The sensor device comprises a stretch sensor directly connected to the body part for obtaining stretch data (100). The stretch sensor is a capacitive or resistive sensor, which changes its capacitance or resistance as a function of elongation. The sensor device is configured to process stretch data from the stretch sensor for determining a stretch value of the body part. The sensor device comprises a processor configured for analysing the stretch data while the body part is in motion； and analysing the stretch data to identify portions (104) of the cyclic stretch data (100) which correspond to motions of the body part. The portions (104) of the stretch data are identified so that the portions (104) contain first and second stretch data points (101, 102) associated with respective first and second motion-phases of the body part. The sensor device analyses the cyclic stretch data (100) to identify first and second stretch values (101, 102) by determining minimum and maximum sensor values (121,122). The sensor device further analyses the cyclic stretch data (100) to identify the portions (104) ensuring that the portions (104) contain portions of an entire period (106) of a cyclic harmonic signal containing first and second stretch data points (101, 102) associated with respective first and second motion-phases of the body part and to distinguish values related to other motion phases (143). The sensor device is also configured for analysing the identified portions (104) of stretch data (100) to determine first and second sensor values (121, 122) of the respective first and second stretch data points (101,102)； and determining stretch values (103) by determining the differences between the first and second sensor values (121, 122).
