Recently, artificial tactile sensors have been studied in attempts to mimic the human sense of touch for various applications, from the simple input function of mobile devices to the complicated finger systems of android robots. To produce artificial psychological feeling, especially ‘pain’, electrical mimic structure of human skin has been studied. Array type tactile sensor can verify the input object...
Structural design factors of sensor units have been studied in order to enhance the sensitivity of pressure sensors based on utilizing a piezoelectric material for an artificial tactile sensor. In this study, we have primarily demonstrated the effect of a square pattern array design in a pressure sensor using ZnO nanowires. Nanowires grown on the edge of cells can be bent easily because of growth...
The electrode-tissue interface plays an important role in neural recordings. Here, we designed and fabricated a flexible electrode array with nanowire structures and poly(3,4-ethylenedioxythiophene) PEDOT on the flexible substrate. ZnO nanowires were used as a nano pillar structure, which increases effective surface area drastically, to decrease electrode impedance. Furthermore, ZnO nanowires was...
Tactile sensors have been received with tremendous attention and developed rapidly for the last few decades. There have been various technologies and transduction methods to innovate the tactile sensor; however, the ability of tactile sensors has left much to be desired. For example, a resistive and a capacitive type sensor, most widely used techniques for touch screen technology and tactile sensor...
