摘要: In this paper we describe a tactile transducer device that is optimized from biomechanical data and has compact, yet modular design. The comprises 6 A— 10 piezoelectric bimorph actuator array with spatial resolution of 1.8 mm 1.2 wide temporal bandwidth. mounting method was improved conventional cantilever to dual-pinned method, giving the ability deform glabrous skin maximally during laterotactile stimulation. results were validated by asking subjects detect features under range operating conditions. display modular, makes use ordinary fabrication methods, can be assembled dismantled in short time for debugging maintenance. It weighs 60 g, it self-contained 150 cm 3 volume may interfaced most computers, provided two analog outputs six digital I/O lines are available. Psychophysical experiments carried out assess its effectiveness rendering virtual features.
