  • Capacitive tactile sensor
    Patent number: 4584625
    Abstract: Contact pressure between the surface of the sensor and the surface of a second object can be measured by a change in capacitance across compressible cells, which comprise the active elements of the sensor. The design allows for the accurate measurement of different pressures at different locations in the area of contact (spatial discrimination), and can be used over a wide range of pressure. As a passive device, it requires external modulation and detection.
