Antibacterial coatings and methods of making the antibacterial coatings are described herein. A first branched polyethylenimine (BPEI) layer is formed and a first glyoxal layer is formed on a surface of the BPEI layer. The first BPEI layer and the first glyoxal layer are cured to form a crosslinked BPEI coating. The first BPEI layer can be modified with superhydrophobic moieties, superhydrophilic moieties, or negatively charged moieties to increase the antifouling characteristics of the coating. The first BPEI layer can be modified with contact-killing bactericidal moieties to increase the bactericidal characteristics of the coating.

An artificial tongue is provided. The artificial tongue includes tongue tissue formed by a bioprinting process, an antenna embedded within the tongue tissue and configured to wirelessly receive power from an external device, a processor embedded within the tongue tissue and operatively coupled to the antenna, and a piezoelectric element embedded within the tongue tissue and operatively coupled to the processor. The piezoelectric element is configured to deform in response to an applied electric bias, and the processor is configured to cause the electric bias to be applied to the piezoelectric element based on the power received by the antenna.

Disclosed are an automatic control system for urinary incontinence with a function of multi-point switching in turn and an intracorporeal apparatus (200) thereof. The intracorporeal apparatus (200) is completely implanted in a body. The intracorporeal apparatus (200) comprises an intracorporeal microcontroller (220) and urethral blockers (230), the intracorporeal microcontroller (220) being configured to control the urethral blockers (230) to block and unblock the urethra. The intracorporeal apparatus (200) comprises at least two urethral blockers (230) provided at different locations on the urethra, i.e., a first urethral blocker (230a) and a second urethral blocker (230b), and the intracorporeal microcontroller (220) is configured to control the at least two urethral blockers (230) to block and unblock the urethra in turn.

A device for controlling urinary flow comprises a fluid inlet and a fluid outlet. The device comprises a valve movable between an open position in which fluid can flow from the fluid inlet to the fluid outlet and a closed position in which fluid flow is blocked between the fluid inlet and the fluid outlet, and an actuator operable to move the valve between the open position and the closed position. The actuator is positioned on a first side of the fluid inletand the fluid outlet is positioned on a second, opposite side of the fluid inlet.

An accommodative intraocular lens includes an optic body having an optical power changing structure. There are two supporting structures disposed opposite one another about the optic body, each supporting structure configured to be connected at a distal end to a ciliary body after implantation in an eye of a patient and connected at a proximal end to the optic body. The two supporting structures are a zeroing supporting structure and an actuating supporting structure. The zeroing supporting structure is configured to not change the optical power of the optic body in an installation mode and an operation mode of the accommodative intraocular lens. An actuating supporting structure is configured to not change the optical power of the optic body in the installation mode but is configured to change the optical power of the optic body in the operation mode of the accommodative intraocular lens.
