Can a fabric offer something more than clothes and fashion? Can we have a sensor or transducer which is made out of something natural and sustainable, yet produced using simple technologies? Those questions were answered by Dr. Dedy Wicaksono, a senior lecturer from Universiti Teknologi Malaysia in a guest lecture organized by Dept. of Electrical Engineering UPH on 22 Sept. 2016. The guest lecture session is part of the regular guest lectures program and integrated into the weekly seminar of Dept. of Electrical engineering UPH.
Dr. Wicaksono?s group from UTM is known as a pioneer in cotton-based microfluidic and MEMS devices. Apart from their extensive works in cotton-based biochemical assay, Dr. Wicaksono also showed his group?s work on cotton-based MEMS transducer in this talk. The fibers in the cotton provide capillary structure for immersing a solution containing nano-particles to functionalize it, while wax, which is traditionally used for drawing pattern in batik (Indonesian traditional clothes) serves as the mask to prevent the solution to get into the fabric. Using either wax patterning and soaking, pipetting, or stamping methods, his group managed to make a silver-nano-particle functionalized resistor, which is flexible (since it is made on cotton fabric) but strain sensitive, so suitable for MEMS sensor. By bending the device, the resistance changes.

Dr. Wicaksono showed some applications e.g. for inclinometer, for click-sensor for human-computer interface glove, and sensors fixed on a lower back of a person to perform pelvic tilt measurement. Nevertheless, Dr. Wicaksono also admitted that repeatability and stability are still a problem for such device, which opens room for improvement in the future.

The guest lecture was attended by around 70 students and staffs from both Dept. of Electrical Engineering and Dept. of Biology of UPH. The discussions were fruitful with many ideas and questions from students and staffs.
