The objective is to design and fabricate one or several circuit board(s) capable of collecting multiple vital signs (ECG, SpO2, Temperature). The design can be a new design or one that is based on an existing reference design if the requirements can be met. If an existing reference design is used, schematics and demo software/firmware will be provided by the freelancer. The requirements are: - Capable of measuring ECG, pulse oximeter (SpO2), and temperature - Use an embedded 32-bit microprocessor with DSP functionality - Data collection of ECG and SpO2 must be simultaneous or with a low, deterministic latency (<1ms) between ECG/SpO2 samples - Sampling of ECG/SpO2 should occur at a rate higher than 100Hz with a good signal-to-noise ratio - Communication over USB/RS232 to a PC host - Onboard storage for at least 10 seconds of ECG/SpO2 data - Powered by a +5V DC power supply. Preferably a USB port. - A touch or infrared sensor for temperature - Firmware/software program...

You will develop the schematics (Gerber Files, BOM, and the Eagle Files) for a PCB for a component device. It is a singular function device with one chip. The main board, which it will need to fit into, and other reference component devices are all open hardware + open software. I will provide links to all of those files. You can use those existing diagrams and specifications to model this piece. The chip you are designing for has complete documentation as well, which I will provide. So, you will take existing schematics for existing PCB components as a starting guide, look at the specifications for the chip ( I will provide all the documentation), and you will design the component piece that includes that chip, and deliver the schematics files. If you have experience designing printed circuit boards (PCBs) this should not take you long.

We have an analog front end design based on this Analog Devices ECG chip: http://www.analog.com/en/products/application-specific/medical/ecg/ad8232.html#product-overview We want to improve our design (to minimize noise, etc.) and implement tests to quantify its accuracy and sensitivity in detecting heartbeats and acquiring the ECG waveform. We use a simulator that we can feed into the board for much of this - more details in a Skype call. We then wish to integrate this analog circuit with microcontroller, Bluetooth, and accessory components to create an integrated device. Primary focus involves all aspects of ECG signal acquisition and processing algorithms. Familiarity with analog ECG front end designs (i.e. ECG acquisition) and proven experience with digital signal processing algorithms for pre-processing, feature recognition and data compression are bonus points.

Project objetive is to package an LCD display module, 2 LED's, on/off switch, 2xAA batteries, battery terminals, and wiring into the constraints of an existing plastic prototype housing with removeable battery cover and make them fully operational for field testing. PCB design and IC programing for LCD module already completed. Also, looking for guidance on how to improve and industrialize for production. Freelancer must be located in Michigan in order to complete this project.
