Abstract

The research paper will present a new energy autonomous system based on micro electrochemical sensors and ultra-thin solar cells, for concentration measurement of different ionic species in natural water sources. It focuses on the following directions: a) new microsensors for detection of nitrites and nitrates in natural water sources and b) low cost autonomous energy system integration and fabrication. The microsensors for nitrates/nitrites and heavy metals will be of electrochemical type, miniaturized, fully integrated, fabricated by micro - nano technology and connected to the electronic module that is providing detection, data acquisition and interpretation and data display. The chronoamperometry and voltammetry characterisation will be presented and the results in nitrites and nitrates detection will be provided. The energy harvester is including a UTSC, a dedicated storage and a power stabilizing device. SnO2, TiO2, ZnO, Pt-Au alloy, FTO materials have been optimised for sensors and solar cells.
