Energy self-sufficient real time bio-signal monitoring and nutrient delivery system based on salinity gradient power generation

An energy self-sufficient system based on salinity gradient power generation, comprising:

• a first Reverse Electro Dialysis (RED) pad and a second RED pad each configured to generate electricity by using a nutrient and/or drug solution;
• a water supply unit configured to supply water to the first RED pad and the second RED pad,
• the first RED pad comprising:
• a first pad supporting body formed with a first electrode pattern,
• a second pad supporting body formed with a second electrode pattern disposed below the first pad supporting body,
• a first skin contact delivery unit disposed below the second pad supporting body,
• a plurality of RED unit cells arranged between the first pad supporting body and the second pad supporting body, and electrically connected to the first electrode pattern and the second electrode pattern, and
• a first terminal disposed on the second pad supporting body and configured to apply a first polarity to the first skin contact delivery unit by being electrically connected to one of the plurality of RED unit cells,
• the second RED pad comprising:
• a third pad supporting body formed with a third electrode pattern,
• a fourth pad supporting body formed with a fourth electrode pattern disposed below the third pad supporting body,
• a second skin contact delivery unit disposed below the fourth pad supporting body,
• a plurality of RED unit cells arranged between the third pad supporting body and the fourth pad supporting body, and electrically connected to the third electrode pattern and the fourth electrode pattern, and
• a second terminal disposed on the fourth pad supporting body and configured to apply a second polarity to the second skin contact delivery unit by being electrically connected to one of the plurality of RED unit cells of the second RED pad,
• wherein, the water supply unit is disposed on the first pad supporting body of the first RED pad, and the third pad supporting body of the second RED pad, and supplies water to the plurality of RED unit cells of the first RED pad and the plurality of RED unit cells of the second RED pad.
