Micro-hairs are profound elements widely used in nature. A great variety of animals use them as sensors to gather information about their surroundings. To artificially fabricate these kinds of sensors, we present a method to produce micro-hairs made of polydimethylsiloxane (PDMS). We investigated the laser micro-drilling of wax and polycarbonate (PC) substrates with a 193-nm ArF laser to produce molds suitable for casting micro-hairs. Especially PC molds lead to high-quality micro-hairs. Thus, laser ablation of PC was intensively studied. In order to obtain micro-hair arrays, experiments where performed to optimize the casting techniques of PDMS in PC molds. The possibilities and limitations of the investigated method of micro-hair production are presented. [ABSTRACT FROM AUTHOR]
