Claim Text:
1. A tactile array sensor comprising: an array of sensor pixels formed by capacitance between overlapped layers of conductor electrodes; one layer of conductor electrodes provided by a common ground electrode laid in substantially spiral configuration with an end coming out radially after the spiral; another layer of conductor electrode pads arranged over the spiral ground electrode and connected to conductors laid in substantially spiral configuration with the ends of the conductors coming out radially in a common direction after the spiral; a means to achieve the said capacitance by pre-insulation of the said conductor electrodes in the second layer by dielectric material coated around the said conductor electrodes individually; a means to hold the said sensor pixels in the said configuration; functioning of sensor pixels by change in capacitance effected by sensing; a means to enable data acquisition from the sensor pixel array, its processing, and display or control of external devices based on the sensed information.
