CASE STUDY EP42HT-2Med: Utilized in Prosthetics and Fully Implantable Medical Devices Among the most challenging medical applications for an epoxy compound are prosthetics and fully implantable medical devices. Not only must the material be capable of withstanding sterilization procedures, it must also exhibit biocompatibility over an extended period of time. Prosthetics and implantable devices must be able to maintain performance levels even when in direct contact with tissue and bodily fluids, and must not introduce toxins or cause injury, a physiological reaction, or immunological rejection....

bonds that connect the electronics with the pads of the sensing platform. The outer membrane, which consisted of a mixture of EP42HT-2Med and polyurethane (PU), was applied by dip-coating the device three times at intervals of one hour. To ensure biocompatibility, the coated device was kept overnight at room temperature and then subjected to a temperature of 80°C for two hours to complete the cure process. After curing, the device was kept at room temperature overnight and then stored in phosphate-buffered saline (PBS) for an additional 24 hours. Results All three prototypes were implanted in...

humid, while open socket designs are more breathable, but are bulky and unaesthetic. Many close-fitting designs are difficult to put on and take off, while looser designs may not be sufficiently stiff to support the arm remnant. Ideally, the socket connecting the artificial arm to the arm remnant should be close-fitting, comfortable to wear, easy to put on and take off, adjustable, lightweight, and self-suspending, among other characteristics. Key Parameters and Requirements At Eindhoven University of Technology, a master’s degree candidate was interested in developing a design for a transradial...
