  • Patent number: 6930590
    Abstract: This application relates to an electrotactile system and method for delivering tactile stimuli to a skin surface of a user. The system includes one or more electrotactile modules each comprising an array of electrodes electrically connected to an integrated circuit. Each integrated circuit has data processing and current driving capability. The current delivered from the integrated circuit to each electrode is relatively small, preferably less than 4 milliamps. The modules may be connected to a flexible PC board by spring-loaded connectors. In one embodiment a plurality of electrotactile modules may be grouped together to from an electrotactile device. Multiple electrotactile devices may in turn be deployed as part of a wearable article for use in virtual reality, telepresence, telerrobotics or other haptic feedback applications. The system is capable receiving and transmitting tactile data via a communication link, such as a conventional data network.
