Abstract
A wearable heat transfer device provides a user with haptic feedback providing sensations of hot or cold. The wearable heat transfer device comprises a heat source/sink and a programmable interface having heat transfer characteristics that are modified based on a signal received by the programmable interface. For example, a thickness of the programmable interface changes based on the received signal, altering heat transfer by the programmable interface. In another example, an electric field is applied to the programmable interface, changing one or more properties of the programmable interface affecting heat transfer.
