A micro angular rate-sensing device is provided. A substrate comprises a plurality of microlocations having microelectrodes connected to a network for connection to a computer to control the voltage and polarity at each of said microelectrodes. According to the invention, both said sets of wheels and said two rails are positioned in such a way as to have an equal load distribution. The co-crosslinking agent is: an \u03b1,\u03b2-unsaturated carboxylic acid having 3 to 8 carbon atoms; andor a metal salt of an \u03b1,\u03b2-unsaturated carboxylic acid having 3 to 8 carbon atoms. A dielectric sleeve is disposed about the coax central conductor adjacent to the first side. If a first threshold is exceeded the user interface is modified, e.
