Vision of the proposed research for developing a self-powered, millifluidic lab-on-a-chip device to determine blood conductivity. a) Schematics and dimensions of the proposed device. The blood layer, copper electrodes, PTFE disc, and PMMA elements form a contact-separation mode TENG system. The blood sample is sandwiched between two PMMA layers and serves as one of the conductive layers. Any change in its electrical conductivity would theoretically change the voltage signal generated by the device. b) Operating principle of this blood-based TENG device. c) The 3D printed device and the type of voltage signal generated by it.
