Molecular receptor-based chemical field-effect transistor (chemfet) devices, systems, and methods for in-situ nitrate monitoring in field soils

摘要: Embodiments include a method for securing membrane material to gate of molecular receptor-based chemical field-effect transistor (CHEMFET). The can casting onto an exposed region the gate, curing material, placing CHEMFET into mold, inserting single application impervious electrically insulative resin and edges by resin, thereby physically preventing lifting off from gate. sensor module. module CHEMFET, amplifier circuit, one or more pins contacting field ground soil, data logger, wireless transceiver, among other components.
