DESCRIPTION:The rapid development of smart material technology and hand hel
 d devices (for example VR controller\, mobile devices) has created high de
 mand for shape changing interfaces in order to provide users with more fun
 ctions in less space and improved usability. However\, the fundamental inc
 ompatibility between flexible displays and rigid actuator components has b
 rought a huge barrier for commercialization of this technology. This semin
 ar addresses a flexible and bendable vibrotactile actuator that can be eas
 ily applied to shape changing hand-held devices. One of the best-establish
 ed technologies for flexible vibrotactile actuators is to use electroactiv
 e polymers (EAPs). There are two types of EAPs\, ionic type and non-ionic 
 type. In an ionic EAP\, the movement of ions inside the polymer creates it
 s actuation. Ionic EAPs allow relatively low input voltage\, but they requ
 ire high electric power (high electric current) for operation because high
  energy is necessary to maintain their deformed shape. Another problem is 
 that their actuation force is not sufficiently strong to allow for clear p
 erception. In contrast\, non-ionic EAPs\, for example\, dielectric EAPs\, 
 have been researched with a keen interest for vibrotactile actuators owing
  to their fast response and high operational efficiency. However\, non-ion
 ic EAPs require a pre-stretching or multi- stacking process to be able to 
 create large force enough to stimulate human mechanoreceptors. This strate
 gy brought a new issue for low durability and/or a complex manufacturing p
 rocess. This seminar addresses a robust and flexible vibrotactile actuator
  using an electro-active plasticized PVC to solve the problem.\n\nCo-spons
