Article Preview

Fabric keyboard is a field of smart textile. It can overcome many disadvantages of conventional keyboard. In order to study the fabric keyboard switch, trapezia structures of two kinds of orifice dimension are designed for example 8 wefts and 16 wefts. Different roots of conductive wires are woven into the down layer of the orifice part for each kind of orifice dimension. 4 and 8 roots of wires are woven for 8 wefts. 4, 8 and 16 roots of wires are woven for 16wefts. Then the immediate regain, connection pressure, connection ratio and contact resistance are tested and analyzed for every kind of fabric keyboard switch. It is concluded that 8 wefts orifice dimension and 8 roots of wires woven into the down layer of the orifice part is a better project. These findings may assist in recommendations regarding the further development of flexible fabric keyboard.
