Abstract
The invention discloses a biosensor for measuring dissolved oxygen at different depths in a water body. The biosensor includes an anode connected by a wire; and the anode is arranged in a base filledwith sediments. The base seals the sediments by a cover plate arranged at the upper end surface. Telescopic rods are arranged at the two sides of the top surface of the baserespectively; connecting rods are arranged at the upper ends of the telescopic rods; and a cathode is fixed between the connecting rods and one end of the cathode is connected with resistors arranged in the telescopic rods by wires. The other ends of the resistors are connected with the anode arranged in the base by wires; and the other end of the cathode is connected with a traction wire. The other end of the traction wirepasses through a support rod arranged at the upper ends of the telescopic rods and is led out from the top of the support rod. The invention aims at providing a biosensor based on a microbial fuel cell; and the dissolved oxygen contents at different depths of a water body are measured conveniently by adjusting the distance between the anode and the cathode.
Description
Technical field [0001] The invention relates to the field of biosensors, in particular to a biosensor for measuring dissolved oxygen at different depths in water bodies. Background technique [0002] Traditional methods for measuring dissolved oxygen mainly include physical, chemical, and electrochemical methods. A variety of dissolved oxygen sensors have been developed, such as fluorescent dissolved oxygen sensors, which are widely used to measure dissolved oxygen concentration. However, these electrode type sensors have several disadvantages, such as expensive electrode materials, difficulty in miniaturization, and electromagnetic interference from other sensors. A microbial fuel cell is a biological electrochemical device, which can directly convert chemical energy into electrical energy through a biological process catalyzed by exogenous microorganisms. Microbial fuel cells and their derived technologies have attracted more and more attention, because they can not only recov...
