Embodiment 1

[0024] The present embodiment provides a polyacrylamide (PAAm) microfiber implanted with monochromatic discrete PEGDA structural color microspheres, and the preparation method includes the following steps:

[0025] Step 1: Prepare a co-flow microfluidic chip, including an inner phase capillary tube and an outer phase capillary tube. The end of the inner phase capillary tube is inserted into the end of the outer phase capillary tube and communicated with the outer phase capillary tube; Insert the dispensing needle into the external phase capillary, and seal and fix it with epoxy resin.

[0026] Step 2, using the sacrificial template method to prepare discrete structural color hydrogel microspheres, the specific method is as follows: preparing silica microspheres composed of nano-silica particles through a single-emulsion microfluidic device; The dried silica microspheres were soaked in a 20% (v / v) PEGDA hydrogel precursor solution, and the hydrogel precursor solution was fully ...

Embodiment 2

[0032] This embodiment provides a polyacrylamide (PAAm) microfiber implanted with two-color and three-color discrete PEGDA structural color microspheres. The preparation method is basically the same as that in Example 1, and the difference is only:

[0033] The number of inner phase capillaries is two. The inner phase solution of the structural color hydrogel microspheres of two colors is prepared, and the inner phase solution is respectively passed into the corresponding inner phase capillary. The distance between the implanted structural color hydrogel microspheres was kept consistent. Specifically, when preparing a co-fluidic microfluidic chip, the two inner phase capillaries can be placed one after the other at the junction of the inner phase capillary tube and the outer phase capillary tube, so that the structural color hydrogel microspheres of different colors appear alternately one after another. .

[0034] Alternatively, the number of inner phase capillaries is three...

Embodiment 3

[0037] This embodiment provides an application, specifically the application of the discrete structured color microsphere implanted fiber in tactile sensing. Under the stimulation of the external environment, such as applying a certain pressure or tension to the fibers, the structural color microspheres implanted in the microfibers will undergo corresponding color changes, accompanied by spectral shift; according to the spectral position of the microfibers, the external Environmental stimuli (gestures, etc.) are identified and monitored.

[0038] Taking microfibers implanted with red discrete structural color microspheres as an example, it is applied to mechanical sensing:

[0039] like image 3 As shown in a, the microspheres in the microfibers exhibit a gradual color change during the compression process. The microfibers implanted with red discrete structural color microspheres are placed in a glass dish, and a thin glass slide is placed over the microfibers, and the micro...

Abstract

The invention discloses a jellyfish whisker inspired discrete structure color microsphere implanted fiber and a preparation method and application thereof, and the preparation method comprises the following steps: step 1, preparing a co-flow micro-fluidic chip comprising an internal phase capillary tube and an external phase capillary tube; step 2, preparing discrete structural color hydrogel microspheres by using a sacrificial template method, and uniformly dispersing the discrete structural color hydrogel microspheres in an aqueous solution with certain viscosity to serve as an internal phase solution; selecting a hydrogel precursor solution which can be rapidly cured and has elasticity as an external phase solution; the internal phase solution and the external phase solution are simultaneously and respectively introduced into an internal phase capillary tube and an external phase capillary tube of a co-flow micro-fluidic chip, benefited from a laminar flow state in a micro-channel, the external phase solution can wrap the internal phase solution and is cured under ultraviolet, and the discrete structure color microsphere implanted fiber is obtained. The preparation method is simple and easy to operate, mass production can be realized, and the prepared microfiber has the advantages of repeatability, convenience in operation, reliable result and the like.

Description

technical field [0001] The invention belongs to the field of biological materials, and relates to a microfiber, in particular to a discrete structural color microsphere implanted fiber inspired by jellyfish tentacles and a preparation method and application thereof. Background technique [0002] Tactile sensors can simulate human skin and have been widely used in everything from electronic skins to human-machine interface systems. The most basic and most important part of a tactile sensor is the sensing part, which can convert environmental information such as pressure, temperature, and humidity into electrical or optical signals for easy monitoring. Among various sensors, microfibers, especially responsive microfibers, can monitor the external environment better due to their flexible and controllable characteristics. However, the existing microfibers can only respond to the physical or chemical changes perceived by the whole fiber, and lack the ability of spatial recogniti...
