CAPACITIVE TACTILE TILE SENSOR |
摘要 |
A capacitive tile tactile sensor is described and includes several groups of individual sensors, each controlled by a dedicated IC. Individual sensors are formed by sensing electrodes 301 on one side of the sensor and a single ground electrode 100 on the other side, the ground electrode is separated from the sensing electrodes by a compressible dielectric layer. A single electrical connection 101 between the ground electrode and the sensing electrode layer allows for routing of all electrical connections including individual electrodes and a ground electrode to appropriate ICs within the same layer 300 using conductive ink or other similar techniques. Stand-alone configurations are described as well as those adapted for communicating with outside control means including a personal computer. Arranging groups of sensors in parallel with each other creates a matrix of sensors while arranging them along a single line creates a linear strip sensor. Using off-the-shelf capacitance-sensing ICs to control a limited number of capacitance sensors allows reducing the number of electrical connections to the sensor array and increasing its reliability. |
