Abstract
In an array type capacitance sensor (1), a slit (2b) is provided between each pair of adjacent ones of multiple movable electrodes (6) on a movable-electrode-side substrate (2) so as to extend in parallel with the movable electrodes (6). This allows providing an array type capacitance sensor capable of being produced inexpensively and measuring pressure precisely and stably even on a curved surface.
Claims7
An array type capacitance sensor comprising:
- a first substrate including at least two rows of first electrodes provided so as to extend in parallel with one another;
- and
- a second substrate, provided so as to face and be at a predetermined distance from the first substrate, including at least two columns of second electrodes which extend in parallel with one another in a direction crossing a direction in which the first electrodes extend,
- the first substrate or the second substrate including a substrate slit section provided between adjacent ones of the first electrodes or of the second electrodes, respectively,
- the substrate slit section having a slit shape, and extending in parallel with the first electrodes or in parallel with the second electrodes, respectively.
