Abstract: A pH-responsive hydrogel, which is synthesized by using mixed pectin and sucralfate treated with a small amount of acid to form a pH-responsive hydrogel. The pH-responsive hydrogel can form a temporary coating on the surface of the gastrointestinal tract to reduce excessive nutrient absorption, and exhibits excellent barrier properties and mucosal adhesion effects, which are useful for reducing blood sugar rise and weight gain, the liver fat accumulation, body fat accumulation and blood low-density lipoprotein that have a significant effect. In addition, the technical principles disclosed in the pH-responsive hydrogel should be applied to other polymer materials to manufacture different pH-responsive hydrogels.

Abstract: A display device enabling external objects to be shown therein comprises a main body formed with a space, a backlight module disposed in the space and a display module disposed in the space. The backlight module comprises a light projection surface, the display and backlight modules are separately disposed by a spacing for at least one external object to locate therein. The display module comprises a transparent display structure, a first optical film disposed on one side of the transparent display structure facing the surface, and a second optical film disposed on the other side. The first optical film enables a light projected by the backlight module and a light reflected by the main body to pass through. The second optical film enables a light from the transparent display structure to pass through, and reflects an ambient light outside the main body.

Abstract: A touch sensor comprises a first electrode, a second electrode arranged spaced apart from the first electrode, and an insulator arranged between the first electrode and the second electrode, wherein at least one of the first electrode and the second electrode is energized, and an energy difference exists between the first electrode and the second electrode. At least one of the first electrode and the second electrode is a stressed electrode. When the stressed electrode is not stressed, no electrical signal is generated, and when the stressed electrode is stressed, the stressed electrode deforms at a stressed point and changes the distance between the stressed point and the other electrode to generate a tunneling current, and the touch sensor generates the electrical signal according to whether the tunneling current is generated. Therefore, the invention solves a limitation of the conventional touch sensor in touching and provides good touching sensitivity.

Abstract: A magnetic energy generation device includes at least two magnetic coil units, two magnetic control units and a rotating unit located in a generator. Each of the magnetic control units is connected with a switchgear, and includes inner magnets, the isolation member and outer magnets. A groove is formed between the inner magnets and the outer magnets of each of the two magnetic control units. The isolation member is located in the groove. The S-pole of each of the inner magnets is located corresponding to the S-pole of the outer magnet corresponding thereto. The N-pole of each of the inner magnets is located corresponding to the N-pole of the outer magnet corresponding thereto so as to have magnetic repelling action to rotate the rotating unit when the isolation members are moved. Magnetic induction is formed between the stator and the rotors to generate induction current.
