Vibration based stimulation or pressure based stimulation are commonly employed in a wide range of devices for medical, therapeutic, and recreational activities. These are designed to be applied against a predetermined region of a user's body. However, there are many instances where it would beneficial to provide the user with a “wearable” device where these one or more predetermined regions of the user's body may be inserted through or disposed within the device providing vibratory and/or pressure based stimulation. Further, such devices may be augmented with other therapeutic means such as light therapy or ultrasonic therapy. Accordingly, a range of wearable devices exploiting hollow shaft motors, electromagnetic actuators, and fluidics are presented.
