“…Attempts have been made to leverage the benefits of smart actuators such as shape memory alloy wires or springs (Wellman et al, 1998), (Velazquez et al, 2005), miniature electrostatic actuators (Jungmann and Schlaak, 2002), electroactive gels (Konyo et al, 2000), specifically developed technologies such as pneumatic bladders (Moy et al, 2000) and miniature electromagnetic solenoids (BenaliKhoudja et al, 2004), even hobby servo-motors (Wagner et al, 2004), or remotized miniature dc motors (Sarakoglou et al, 2005).…”

This paper presents a tactile transducer device that is optimized from biomechanical data and has a compact, yet modular design. The tactile transducer comprises a 6 × 10 piezo bimorph actuator array with a spatial resolution of 1.8 × 1.2 millimeters and a wide temporal bandwidth. The actuator mounting method was improved from a conventional cantilever method to a dual-pinned method, giving the actuator the capability of maximally deforming glabrous skin for laterotactile stimulation. The results were validated using a psychophysical method. The tactile display device is modular, appeals to ordinary fabrication methods, and can be assembled and dismantled in a short time for debugging and maintenance. It weighs 60 g, it is self-contained in a 150 cm 3 volume and may be interfaced to most computers, provided that two analog outputs and six digital io lines are available. Psychophysical experiments were carried out to assess its effectiveness in rendering virtual tactile features.

“…These approaches differ by the actuator technology employed, by the manner in which tactile signals are delivered to the skin, by the type of tactile signals they produce, by practical factors such as bulk and power, as well as by the range of sensations that they can mediate. Many principles able to produce movement in a small space have been explored, including miniature solenoids that vibrate steel membrane elements by variable reluctance [1], surface acoustic waves that modify the sliding interaction between a surface and a plate [2], electrogel lamellae that push against the skin [3], and pneumatically-activated dimples rising out of a surface [4]. A more complete survey of tactile display technologies can be found in [5].…”

Abstract-This paper describes the design, construction, and initial evaluation of a handheld information device that supports combined tactile and graphical interaction. The design comprises a liquid crystal graphic display co-located with a miniature, low-power, distributed tactile transducer. This transducer can create electronically-controlled lateral skin deformation patterns which give the sensation of sliding over small shapes. It is integrated within a slider mechanism to control scrolling. It also functions as a detent when pushing on it. Tactile feedback and the combination of visual and tactile feedback in a mobile context enable the development of new functions, such as multimodal navigation within large graphic spaces.

“…Various mechanisms of tactile device have been researched; pin-arrays utilizing piezoelectric actuators [2], shape memory alloys [3], piezoelectric ceramics [4], ionic conductive polymer gel films [5], polymer fabrics [6], electric motors [7] and MR fluid. The rheological properties of MR fluid are reversibly and instantaneously changed by applying magnetic field to the fluid domain [8].…”
