We have fabricated a bunch electrochemical sensor that is capable of detecting certain analyte molecules from human urine. The sensors fabricated is generating very low current ie ranging from 100nA to 1 microampere. We want to build a readout circuit that can effectively measure the current and send the signal to IoT based microcontroller (Arduino, particle photon, esp). The detailed project description is attached herein...

I can design it very efficiently for you. If you are looking for precision design, please have a discussion and get going. I have very good working experience in nanoamp or microvolt scale and having precision measuring equipments to validate the design as well. My bid includes analog part design only. However, if you need me to assist in complete product design that includes IoT part handling, then we can negotiate on the best pricing. Thanks. I look forward to hearing from you. Best Regards... Roy

For Amperemetric sensors, we need to have I to V converter (Op amp based) which converts current to voltage. and Then all analog voltages to be converted to digital using ADC for input to IoT based controller. But current is very low , very high sensitivity circuit is required...

we have design very low ultra power current and voltage amplifiers to detect very low current and also made a circuit to work as a ac amplifier as in low current amplification there is a chanse of noise to be add and to remove that component we designed high pass filter . pls also share that is input continuous or coming in pulse form.

Hi! I am Carlos, a young Systems Electronics Engineer. I am sure I can help you with this project because of my experience in this kind of designs. Some of my main skills are: • Digital systems design with VHDL. • Embedded software design for ARM arquitecture, such as ARM Cortex Mx microcontrollers. • Embedded Linux software design. I have experience in SoCs design, such as Xilinx’s Zynq. For those SoCs I can compile a custom Linux and run it on the board if you need to. • Analog design. I can design your analog circuit using OPAMPs and transistors combination. I have experience in laboratory analog design improvement as well. • PCB board design. I can design your PCB board using some well-known environments, such as Eagle or DesignSpark. If you need more information, please do not hesitate in contact me! Best regards, Carlos.
