|
Sukho Park(Chonnam National University, Republic of Korea) |
| Poly-NIPAAM has been widely used in tissue engineering and
micro-structure in micro-fluidic applications. This paper proposes a photo-polymerization method of NIPAAM using UV LED
microscope. Through the combination of a commercialized UV LED, optical components, an objective lens and X-Y-Z
motorized stage, we fabricated a UV LED microscope for the photo-polymerization of NIPAAM. Finally, we can directly
fabricate micro-structures of poly-NIPAAM by using the proposed UV LED microscope. |

Eunpyo Choi, Kilsung Kwon, Daejoong Kim, Jungyul Park(Sogang University, Republic of Korea) |
| In this paper, we present a novel method to form three dimensional ion-selective nanochannel networks between two microfluidic channels using geometrically controlled in situ self-assembled nanoparticles. These assembled networks have a role as ion-selective membranes with high ionic selectivity and high ionic flux or low fluidic resistance, which was trade-off relation and impossible to achieve both at the same time heretofore. As a promising application, we present a high efficient microenergy harvesting device based on reverse electrodialysis. |

| This paper presents method of fabricating a pulverized drug, Lapatinib (Tykerb®), loaded micro chambers made of a biodegradable polymer, poly (ε-caprolactone) (PCL), for bacteria-based microrobots. Lapatinib is encapsulated between PCL films by the screen printing method and x-ray lithography process is then used for fabrication of micro chambers. The fabrication results indicate that the proposed method is appropriate for fabrication of biodegradable polymeric micro chambers encapsulated with the pulverized drug for bacteria-based microrobots. |

Motion Analysis of Upper Limb for a Planar Cable-Driven Parallel Robots toward Upper Limb Rehabilitation |
|
XueJun Jin, Dae Ik Jun, Xuemei Jin, Sukho Park, Jong-Oh Park, Seong Young Ko(Chonnam National University, Republic of Korea) |
| O Nowadays robotic technology is widely used in rehabilitation especially in stroke rehabilitation
O A planar cable-driven parallel for upper limb rehabilitation is currently under development
O This paper presents motion analysis of upper limb to design a 3-DOF upper limb rehabilitation robot
O The proposed robot is to provide the relatively large workspace and to be less dangerous in the situation of robot’s malfunction due to reduced moving part
O Since our rehabilitation is being designed to have a planar workspace, the motion of upper limb is also analyzed in a plane |

|
This paper proves a patient’s motor intention method which can be applied to an knee joint rehabilitation robot. We suggest the recognition delay and the recognition rate for quantifying the performance of intention recognition system. And they are added to our previous research. As a result applying our intention recognition system using EMG signals and hidden Markov model to a knee rehabilitation robot, the robot has followed properly with the recognition delay shorter than 200 msec and the recognition rate of 94.23 %. This method could be applied to an gait rehabilitation robot. |
