[0042] Example 1: A manufacturing process of a single-airway polymer soft finger, comprising the following steps:
[0043] Step 1: In the mold with polytetrafluoroethylene as the matrix, spray a certain amount of release agent in the mold to ensure that the obtained rubber can be easily and completely separated from the mold.
[0044] Step 2: Configure the Ecoflex 00-30 prepolymer mixture, put it in the ultrasonic vibration pool for 5 minutes, and put it into the mold with a pouring weight of 22g.
[0045] Step 3: Put the mold in a vacuum drying oven to evacuate to remove air bubbles. After no bubbles are produced on the surface of Ecoflex00-30, put the mold in a 60°C electric constant temperature blast dryer for constant temperature curing for 30 minutes.
[0046] Step 4: Take out the mold and put it into a cylindrical mold of a certain size. Prepare 15g of PDMS with a mass ratio of prepolymer and curing agent of 10:1, and place it in an ultrasonic vibration pool for 5 minut...

[0048] Example 2: A manufacturing process of a single-airway polymer soft finger, comprising the following steps:
[0049] Step 1: Spray a certain amount of release agent in the mold with polytetrafluoroethylene as the matrix to ensure that the obtained rubber can be easily and completely separated from the mold;
[0050] Step 2: Prepare 15g of PDMS with a mass ratio of prepolymer and curing agent of 10:1, and place it in an ultrasonic vibration pool for 5 minutes. Put the PDMS prepolymer mixture in the mold.
[0051] Step 3: Put the mold into a vacuum drying oven to evacuate and keep the vacuum state for 15 minutes to remove air bubbles. After no bubbles are generated on the PDMS surface, the mold is placed in a 60°C electric constant temperature blast dryer for constant temperature curing for two hours.
[0052] Step 4: Take out the mold and put it into a cylindrical mold of a certain size. Then pour the Ecoflex00-30 prepolymer mixture into the mold, and the pouring weigh...

[0057] Step 3: Put the rigid mold into a vacuum drying oven to evacuate and keep the vacuum state for 15 minutes to remove air bubbles. After no bubbles are generated on the surface of PDMS, the mold is placed in a 60°C electric constant temperature blast dryer for constant temperature curing for 6 hours.
[0058] Step 4: Take out the mold and put it into a cylindrical mold of a certain size. Then pour the Ecoflex00-30 prepolymer mixture into the mold, and the pouring...
