Capacitance Sensors Based on Nanotube Supercondensers

详细

A design of a capacitance sensor, which remains highly sensitive while allowing the significant miniaturization of its sensitive element, the condenser, is proposed. For this purpose, supercondensers based on electroconducting and insulating nanotubes are used. The presented calculations show the possibility, in principle, to create pressure and displacement capacitance sensors on this basis with a sensitivity that is 5–6 orders of magnitude higher than the sensitivity of those based on classical carbon nanotubes. Such sensors can be used in medicine, robotics, and nanoelectronics.
