Flexible capacitive humidity sensor including porous material

摘要

The present invention relates to a capacitive sensor, and more particularly, to a capacitive sensor including a porous member. The present invention includes a substrate made of a flexible material, a lower electrode, an upper electrode, a moisture-reducing part that is sandwiched between the upper electrode and the lower electrode and capable of adsorbing moisture, and at least one of the upper electrode, the lower electrode and the moisture-reducing part is a porous member A capacitive sensor including a phosphorus porous member is proposed. With the configuration as described above, there is an effect of increasing the capacity of the humidity sensor, enabling sensing even at a small value, and facilitating deformation of the entire shape. In addition, by enabling heating as well as sensing, there is an effect of enhancing reactivity and preventing heat from being transferred to the outside of the sensor.
