Benefits of technology

This patented describes a new way of making a special device that uses specific properties from certain types of elastic plates called IMPC (Isolated Metal Sheet Conductive) instead of just one piece of metal sheet). These devices have unique features like being able to sense and respond quickly when they change shape due to external stimuli such as pressure changes. They also allow for more complex movements than previous designs without losing their functionality over time. Overall this innovative design allows for better performance capabilities while maintaining ease of use by users who want flexibility at work.

Problems solved by technology

This patents discuss how soft electronic systems like muscle tissue work better than hard ones due to their ability to change shape without being affected mechanically. Soft electronics offer an exciting new way to create smart structures called “flexors” that allow us to control things through physical interactions. These types of MEAs include organic molecular crystals, plastic elastometers, conductive rubber sheets, metal foils, etc., each having its own unique properties and capabilities.

Embodiment 1

[0029] Such as figure 1 As shown, the present embodiment is based on the array type flexible curved surface self-sensing driver of IPMC. A plurality of sheet electrodes 2 are arranged in a 3×3 square array on the upper and lower surfaces of the polyelectrolyte flexible substrate layer 1, and are located on the upper surface. The plurality of sheet electrodes on the surface are symmetrical to the plurality of sheet electrodes on the lower surface;

[0030] Two symmetrical sheet electrodes and a part of polyelectrolyte flexible matrix layer clamped between the two sheet electrodes form a functional element, the functional element is a sensing functional element A or an actuating functional element B; on the self-sensing driver at the same time a presence sensing function and an actuation function;

[0031] There are circuits 3 extending outwards from the edge of each sheet electrode, and each circuit is drawn from one side of the polyelectrolyte flexible matrix layer and connec...

Embodiment 2

[0047] The structure and size of the array type flexible curved surface self-sensing driver based on IPMC in this embodiment are the same as those in Embodiment 1, and are specifically prepared according to the following steps:

[0048] (1) The Nafion-117 ion membrane produced by DuPont Company of the United States was used as the flexible substrate layer, and it was cut to a rectangle of 100mm×70mm.

[0049] (2) as figure 2 In the form shown, the transparent glue is used as a mask material to cover the part on the surface of the polyelectrolyte flexible matrix layer that does not need to be plated with sheet electrodes and circuits for positioning.

[0050] (3) Cut the gold foil into the shape of a sheet electrode extending with a circuit, and cover it on one side of the flexible substrate layer, and then flatten it and perform hot pressing on a tablet press. The tablet pressing temperature is 60 ° C, pressure 0.6MPa, and the duration is 4min, so as to form an electrode lay...

Embodiment 3

[0054] The structure and size of the array type flexible curved surface self-sensing driver based on IPMC in this embodiment are the same as those in Embodiment 1, and are specifically prepared according to the following steps:

[0055] (1) The Nafion-117 ion membrane produced by DuPont Company of the United States was used as the polyelectrolyte flexible matrix layer, and it was cut into a rectangle of 100mm×70mm.

[0056] (2) Mix the liquid Nafion-117 ionic membrane and the flocculent carbon nanotube material at a mass ratio of 1:2, and stir evenly with magnetic force to make a mixed solution;

[0057] Cast the mixed solution in a mold with a specification of 10cm (thickness)×7cm×10cm, and heat the mold evenly at a heating temperature of 80°C. After the mixed solution evaporates and forms a film, stop heating to obtain the electrode layer film of the required specification .

[0058] (3) Both surfaces of the Nafion-117 ionic membrane are pasted with an electrode layer film,...

Abstract

The present invention discloses an array flexible curved surface self-sensing driver based on IPMC and a preparation method thereof. A plurality of sheet-shaped electrodes is arranged in an array mode at the upper surface and the lower surface of a polyelectrolyte flexible matrix layer; the sheet-shape electrodes at the upper surface and the lower surface are symmetrically one-by-one, and the two symmetrical electrodes and the partial polyelectrolyte flexible matrix layer clamped between the two sheet-shaped electrodes form a sensing function element or an actuating function element; and the edges of each sheet-shaped electrode extended outwards with circuits. The preparation method comprises: electrodes and circuits are formed on the polyelectrolyte flexible matrix layer through a mask mode and a laser cutting mode after integration plating. The self-sensing driver is simple in technology and employs the sensing function and the actuating function of the IPMC to realize accurate control of curer surface deformation position of the flexible curved surface driver.
