The invention provides a
dot matrix type pressure distribution sensor based on a carbon
nano tube and a preparation method thereof, which belongs to the technical field of sensing devices for dental clinical examination. The
dot matrix type pressure distribution sensor comprises a first film substrate, a second film substrate, a group of first electrodes, a group of second electrodes, a first insulating layer and a second insulating layer, wherein the first and the second insulating
layers are positioned between the first and the second film substrates; the first and the second film substrates are both
polyester films; and the first electrodes, the second electrodes, first connecting wires, second connecting wires, first
electrode terminals and second
electrode terminals are all made of silver. The
dot matrix type pressure distribution sensor has the advantages that the recoverability and the elasticity are outstanding, the occlusive service life reaches more than 300 times; the excellent clinical effects on tooth correction, false tooth implantation and health care are guaranteed; each imperceptible point on an end surface is guaranteed to be measured in the
occlusal contact process of the upper and the lower teeth; and the
processing steps are simple and not redundant, so not only can comprehensive reflection of the technical effects of the pressure distribution sensor be guaranteed, but the requirement of industrialized
mass production can be satisfied.
