Disclosed is an energy self-sufficient real time bio-signal monitoring and nutrient and/or drug delivery system based on salinity gradient power generation. The energy self-sufficient real time bio-signal monitoring and/or nutrient delivery system based on salinity gradient power generation includes: an electricity generation and nutrient and/or drug delivery module including a reverse electrodialysis device which generates electricity by using a nutrient and/or drug solution and discharge a diluted nutrient solution; and a bio-signal measuring unit inserted into the electricity generation and nutrient and/or drug delivery module and configured to receive electricity from the electricity generation and nutrient and/or drug delivery module and measure a bio-signal.

Disclosed is a direct synthesis method of nanostructured catalyst particles on surfaces of various supports. In the disclosed synthesis method of a catalyst structure having a plurality of nanostructured catalyst particles dispersed in a support by a one-step process using a high-temperature high-pressure closed reactor, the one-step process includes supplying the support and a catalyst source into the high-temperature high-pressure closed reactor; supplying an atmosphere forming gas of the reactor into the reactor; perfectly sealing the high-temperature high-pressure closed reactor and heating the reactor to produce the catalyst structure in the reactor under self-generated pressure and synthesis temperature conditions, the catalyst structure including the plurality of nanostructured catalyst particles dispersed in the support; removing internal gases of the reactor to allow the reactor to be in a high-temperature, atmospheric pressure state and supplying an inert gas into the reactor to remove unreacted materials and byproducts remaining in the reactor; and cooling the reactor to room temperature while supplying the inert gas to synthesize the catalyst structure.
