Devices that change size/shape via osmotic pressure |
摘要 |
Devices implantable in animal bodies, possibly configured as self-inflating spinal disc prostheses. Alternatively, non-implantable water-desalination and/or purification devices. The devices include specified types of water-absorbing solute encapsulated by non-porous, water-permeable polymer membranes having specified properties. Also, methods of using the devices in biomedical applications or water treatment.
