IROS - Interactive haptic display based on soft actuator and soft sensor
2017 IEEE RSJ International Conference on Intelligent Robots and Systems (IROS), 2017Co-Authors: Hoa Phung, Canh Toan Nguyen, Tien Dat Nguyen, Phi Tien Hoang, Hosang Jung, Hyouk Ryeol ChoiAbstract:This paper demonstrates a new haptic display based on soft actuator and soft sensor. The device consists of an array Rigid Coupling actuator and an array tactile sensor which configured sensor located on the top of actuator. The actuator includes a frame with Rigid Coupling made by silicone and a dielectric elastomer actuator(DEA). The movement of the DEA is transferred to touch pad via Rigid Coupling. Thus, it provides a soft, comport touch feeling and eliminates the danger of applying high voltage to the human skin. The actuator can work at a wide range frequency of 0–150 Hz and produce sufficient force of 50 mN over the human hand threshold. The tactile sensor can measure the pressure, locate the objects and send the feedback signals to control the actuator. In this work, a 8×12 haptic tactile display is made with high resolution. In addition, the high voltage signal processing also developed to generate variable 0–3.5 kV, and can control individual cell by using the dynamic scanning actuation algorithm. Then, it can display any shape such as a circle, a smile/sad face, a star, etc. In the future, we will build the “emotion touch pad” system which can transfer a person's emotion to another one via internet.

Tactile display with Rigid Coupling based on soft actuator
Meccanica, 2015Co-Authors: Hoa Phung, Choong Han Lee, Ja Choon Koo, Jae-do Nam, Uikyum Kim, Hyungpil Moon, Canh Toan Nguyen, Tien Dat Nguyen, Donghyouk Lee, Hyouk Ryeol ChoiAbstract:The tactile display is a device which physically stimulates the human skin to reproduce the feel of touch. This paper presents a novel tactile display device driven by a dielectric elastomer actuator. The device adopts an indirect actuation method by using a Rigid Coupling, which aims to avoid direct contact of the human skin with the actuator. The Rigid Coupling is made of silicone to transmit the movement of the actuator to the touch layer located on the top surface of the Coupling and provides the feeling of softness on contact. The device produces displacement about 350–140 μm at 0.3–10 Hz, which meets frequency requirements for simulating the Merkel cells as well as Meissner corpuscle. The force to simulate the fingertips can be exerted over 44 mN. This work describes its design, analysis and fabrication method in details with its experimental evaluations.

RO-MAN - Preliminary design and fabrication of smart handheld surgical tool with tactile feedback
2013 IEEE RO-MAN, 2013Co-Authors: Choong Han Lee, Dong Hyuk Lee, Ja Choon Koo, Jae-do Nam, Hyungpil Moon, Canh Toan Nguyen, Ui Kyeom Kim, Dat Tien Nguyen, Hyouk Ryeol ChoiAbstract:In this paper, we present a smart handheld surgical tool with tactile feedback to help microsurgery. This device consists of force sensors attached to the tool tip and tactile displays on the position of the fingerhold. The sensor is capacitive one and measures not only the magnitude of force, but also the direction of force. The sensor can measure 9N of lateral forces along x-y-z direction. The tactile display is based on dielectric elastomer actuators and made up of three Rigid Coupling tactile display modules. The tactile displays provide stimuli of 170μm displacement and frequency of 10Hz at the surgeons fingertips. We fabricate the device and its performances are experimentally validated.

Tactile display with Rigid Coupling
Proc. SPIE, 2012Co-Authors: Hyung Seok Lee, Nguyen Canh Toan, Dea Gyeong Kim, Choong Han Lee, Jeongheon Han, Dong Hyuk Lee, Ja Choon Koo, Jae-do Nam, Uikyum Kim, Nguyen Ngoc Linh, Hyungpil Moon, H. G. ChoiAbstract:In this paper, we propose a tactile display with a Rigid Coupling based on Dielectric Elastomer Actuator. The proposed design of the tactile display is explained and its basic operational principles are discussed. It consists of three parts, that is, actuator layer, Coupling and upper layer. The Rigid Coupling is sandwiched between them. Because of the simplicity of the design, the fabrication is extremely easy, that is just to bond the upper layer to the actuator layer after making EAP actuator sheet and upper layer. The device is fabricated with multiply stacked actuators and its effectiveness is validated experimentally.
