Using an electroactive polymer (EAP) actuator to deliver haptic force sensation to a user is a haptic device and method. An electroactive polymer actuator that responds to input signals from the sensor provides a haptic feedback force to the user caused by motion of the actuator is also a part of the device that detects a user’s touch on a touch surface.
In general, the present invention pertains to interface devices that let people interact with computers, and in particular to inexpensive computer interface devices that let users give input to computers and receive haptic feedback from those same computers.
A user can interact with an environment that a computer displays to carry out operations and tasks on the computer, such as playing games, engaging in simulations or virtual reality environments, utilizing computer aided design systems, operating a graphical user interface (GUI), navigating websites, etc.
A mouse, joystick, trackball, gamepad, steering wheel, stylus, tablet, pressure-sensitive sphere, or similar device connected to the computer system controlling the displayed world is a typical human-computer interface device used for this type of interaction. Usually, when a user moves a physical manipulandum like a mouse or joystick handle, the computer modifies its environment.
Through sensors on the interface device that transmit locative signals to the computer, the computer detects the user’s manipulation of the user object. In other applications, interface tools like remote controllers let a user interact with an electronic gadget or appliance’s features. For haptic applications, the quality, amplitude, and frequency of the forces that interact between a human and an actuator are crucial.
These features can be offered by a range of Electro-Active Polymer (EAP) based actuators together with quiet operation, low weight, high power density, and quick response. In order to measure heartbeats, a rolled Dielectric Elastomer Actuator (DEA) is employed in this research as an example of telepresence technology. In this experiment, cardiac signals were obtained wirelessly from a distance.
The Global EV electroactive polymer haptics market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2022 to 2030.
The consumer experience with their favorite electronics is evolving thanks to ViviTouch technology. The technology is based on thin polymer films that can swiftly stretch and contract, much like artificial muscles, and was created by Artificial Muscle, Inc., a wholly owned subsidiary of Bayer MaterialScience.
When voltage is applied, electroactive polymers (EAPs) can alter shape and convert electrical energy into motion. Users are submerged in a high-definition (HD) world of tactile experience thanks to ViviTouch’s haptic replies.
For creating HD haptic effects, equipment with millisecond response times is ideal. The technology is now widely used, and the consumer electronics business is showing a lot of interest in it, particularly for gaming and headphone applications. The inefficiencies in the traditional electro-magnetic actuators frequently employed in robotics were the original target of the technology.
