Zusammenfassung:The present invention relates to a pressure-sensitive input device comprising a touch layer (4), a frame (6), a first strain gauge device (12), and a second strain gauge device (13). The touch layer (4) is configured to change a dimension of the touch layer (4) due to a force being applied to the touch layer (4). The touch layer (4) is attached along an edge (5) of the touch layer (4) to the frame (6). The first strain gauge device (12) is arranged at the touch layer (4) and configured to detect a strain in a first direction (10) essentially along the edge (5) of the touch layer (4). The second strain gauge device (13) is arranged at the touch layer (4) and configured to detect a strain in a second direction (11) different from the first direction (10).
