The apparatus and methods of the present invention provide improved accuracy of response for a tactile transducer included in a body-mounted device such as a headphone, VR/AR headset or similar device. Accuracy is increased through the application of digital signal processing, such as with Infinite Impulse Response filters or Finite Impulse Response filters.

Tactile transducer with digital signal processing for improved fidelity

A vibration module for applying vibrational tractions to a wearer's skin is presented. Use of the vibration module in headphones is illustrated for providing tactile sensations of low frequency for music, for massage, and for electrical recording and stimulation of the wearer. Damped, planar, electromagnetically-actuated vibration modules of the moving magnet type are presented in theory and reduced to practice, and shown to provide a substantially uniform frequency response over the range 40-200 Hz with a minimum of unwanted audio.

Systems and methods for generating damped electromagnetically actuated planar motion for audio-frequency vibrations

The apparatus and methods of the present invention provide quiet, compact, robust hardware that can accurately produce a wide range of tactile frequencies at a perceptually constant intensity. For greater expressiveness, some apparatus for moving the skin in multiple axes are also disclosed. Signal processing methods are presented to enhance the user's experience of audio spatialization. The methods transform audio signals into directional tactile cues matched to the time resolution of the skin, and which exploit directional tactile illusions.

Apparatus and methods for audio-tactile spatialization of sound and perception of bass

An apparatus includes a substrate, a dielectric elastomer transducer electrically coupled to the substrate, and a compliant electrically conductive housing coupled to the dielectric elastomer transducer. A portion of the compliant electrically conductive housing projects through an opening defined in a housing. A method is disclosed for making the apparatus.

Rolled and compliant dielectric elastomer actuators

A dielectric elastomer transducer comprising a first and second ends and first and second electrical terminals connected to the respective first and second ends of the dielectric elastomer transducer is provided. A system also includes a substrate, a conductive flexure with one end attached to the substrate and another end configured to receive a load. A first electrical connector pin is attached to the flexure to receive the first electrical terminal and a second electrical connector pin is attached to the substrate to receive the second electrical terminal. Another system also includes a living hinge flexibly coupling two separate substrates, where at least one of the substrates is movable in response to energizing the dielectric elastomer transducer.

Electrical interconnect terminals for rolled dielectric elastomer transducers

Apparatus and methods for altering the appearance of wearable device are disclosed. The apparatus may statically or dynamically alter the appearance of the wearable.

Apparatus and methods for altering the appearance of wearable devices

A process for producing a corrugated electrode for use in an electroactive polymer cartridge is disclosed. A laminated web comprising a support sheet laminated to a dielectric elastomer film is positioned. The support sheet defines areas exposing portions of the dielectric elastomer film. A force is applied to the positioned laminated web to stretch the laminated support sheet-dielectric elastomer film web in a direction that is orthogonal to a plane defined by the web. An electrically conductive material is applied to the laminated support sheet-dielectric elastomer film web while the laminated support sheet-dielectric elastomer film web is in a stretched state. The laminated support sheet-dielectric elastomer film web is relaxed to form the corrugated electrode on the dielectric elastomer film portion of the web.

Roll-to-roll manufacturing processes for producing self-healing electroactive polymer devices

A method for fabricating electroactive polymer transducers, the includes providing an electroactive polymer film comprising an elastomeric dielectric polymer, forming an array of electrodes on the film, and sandwiching the electrode array between a top and bottom array of frame components to form an array of electroactive polymer transducers.

Method of manufacturing electroactive polymer transducers for sensory feedback applications

Dielectric elastomer or electroactive polymer film transducers configured to minimize high electrical field gradients that can lead to partial discharge and corona.
