Embodiment Construction

[0030] figure 1 An exploded view of an example embodiment of the first aspect of the invention is shown. The stretchable bidirectional capacitive pressure sensor 20 includes a first elastic sheet 22 , a microstructure 24 and a second elastic sheet 26 . The first elastic piece 22 and the second elastic piece 26 are made of dielectric material. A series of wires 221 extending in parallel are located on or in the first elastic piece 22 . The microstructure 24 includes a plurality of elastic struts 241 made of a dielectric material. Each pillar in this embodiment is a cuboid, preferably a rectangular cuboid with a width of about 6 μm and a height of less than 300 μm. Although from figure 1 It cannot be seen in the exploded view, but the two opposite faces of the rectangular parallelepiped pillar are bound to the first elastic piece 22 and the second elastic piece 26 indirectly or directly. A series of wires 261 extending in parallel are located on or in the second elastic pie...

Abstract

A stretchable bidirectional capacitive pressure sensor (20) comprising: a first elastomeric sheet (22) made from a dielectric material, with a series of conductor lines (221) located on or in the first elastomeric sheet; a second elastomeric sheet (28) made from a dielectric material, with a series of conductor lines (261) located on or in the second elastomeric sheet; wherein the conductor lines of the first elastomeric sheet are substantially orthogonal to the conductor lines of the second elastomeric sheet; a microstructure comprising a plurality of elastomeric pillars (241) made from a dielectric material, disposed between the elastomeric sheets; wherein the microstructure is bonded to both the first and second elastomeric sheets so that the bidirectional sensor can register positive and negative pressure by the movement of the first and second elastomeric sheets. A further aspect of the invention discloses a method of collecting data related to fluid flow over an object by using a two-dimensional capacitive pressure sensor.

Description

technical field [0001] The present invention generally relates to a sensor for measuring pressure. More specifically, the present invention relates to a stretchable bidirectional capacitive pressure sensor having two elastic sheets with a series of embedded carbon nanotube electrodes separated by elastic microstructures. Furthermore, the present invention relates to a method for collecting data related to fluid flowing through an object, and more particularly, to a method for collecting data related to fluid flowing through an object by using a stretchable two-dimensional pressure sensor . Background technique [0002] Flexible and / or stretchable pressure sensors are a recent development and an area of ​​intense research interest. These sensors are usually two-dimensional sensors that can measure the force acting on an area by taking a reading of the area. The sensing mechanisms used in flexible / stretchable sensors can vary, but they can be categorized as piezoresistive, ...
