Abstract: A miniature three degree-of-freedom actuator provides haptic stimulation via skin deformation on a user’s forearm. The device, which consists of a parallel delta-mechanism linkage driven by three servo motors, can produce skin stretch, normal force, and low frequency vibration. The 2 cm diameter footprint of the device enables multiple devices to be packed together with a high density, enabling an array of stimulation locations. The device was used to measure the directional skin stretch discriminability of human subjects on the forearm, and preliminary tests suggest that average angular error is approximately 27 degrees.
