We constructed these bats out of felt material. We then equipped them with sensors that made them scream and react when people touched and approached them in physical space.
Conductive yarn is pinned on the body of the bats which are then connected to the capacitive sensor. Meaning when a hand comes at a proximity of the bat, it already starts to scream. It is touch sensitive, the more you touch, the higher the scream. The same yarn was also put inside the mouth of the bat which triggered a biting sound that was sampled using a chair.
