A method including receiving sound data captured by a wearable device of the user, the sound data indicative of contact between a first portion of the user wearing the wearable device and a second portion of the user wearing the wearable device; receiving motion data captured by the wearable device of the user, the motion data indicative of at least a movement of the first portion of the user wearing the wearable device; and determining, by a processor, based at least in part on the sound data and the motion data, a user input associated with the contact between a first portion of the user wearing the wearable device and a second portion of the user wearing the wearable device and the movement of the first portion of the user wearing the wearable device.

A vibration transducer for sensing vibrations includes a first flexible triboelectric member, a second flexible triboelectric member, a plurality of attachment points, a first electrode and a second electrode. The first flexible triboelectric member includes a first triboelectric layer and a material being on a first position on a triboelectric series. A conductive layer is deposited on the second side thereof. The second flexible triboelectric member includes a second triboelectric layer and a material being on a second position on the triboelectric series that is different from the first position on the triboelectric series. The second triboelectric member is adjacent to the first flexible triboelectric member. When the first triboelectric member comes into and out of contact with the second triboelectric member as a result of the vibrations, a triboelectric potential difference having a variable intensity corresponding to the vibrations can be sensed between the first and second triboelectric members.
