**Names:** Madhavan Nair (mgnair2), Samhita Inampudi (sinamp2) , and Jack Rueth (rueth2) **Title:** Bubz, a 12-lead Wire-free EKG **Problem:** In the medical field, EKG’s are critical to use to understand heart health and other kinds of diseases in the human body. One of the issues with the current way EKG’s are used is that there are too many wires. In emergency situations, these wires make it difficult for doctors to do their job efficiently. In addition to that, EKG’s are generally bulky and hard to transport to underserved communities. In the market right now, there is a solution that only provides a frontal view of the heart which does not have the data required to diagnose heart attacks, kidney failure, and other fatal organ issues. **Solution:** We propose to build a 12-lead wire-free EKG. In our solution we want to create small suction bulbs to conveniently assess a patient’s heart health. Each of these bulbs will contain a circuit board with wireless connectivity to transmit a PQRST wave in real-time to the data display along with a power supply (potentially rechargeable if time permits). Using Body Surface Potential Mapping, we can measure the electrical potential gradient at various points of the body to create a vector mapping including these 12 views from 2 different planes (vertical and horizontal). Each bulb would have to have some form of power supply and bluetooth/wireless transmission, in addition to the actual measurement mechanism/filtration process and data visualization. We hope that this solution would make the process of getting an EKG faster, easier, and more efficient. **Solution Components:** 3D printed body - Functioning body that can house our PCB and power supply while also being adhesive to the skin Bluetooth modules - Module that transmits PQRST data from the bulb to the computer/screen. - Transmits data to receiver hub Power supply - 3.3 volt battery for powering amplifier circuit and Bluetooth module EKG board works - Instrumentation amplifiers for filtering and amplification of skin potential difference signals. Will likely use some combination of op amps, resistors, and capacitors for refining signal. We are also considering the possibility of using a variable resistor to have flexibility during PCB design. Data processing/visualization - Noise reduction. EKGs are on the scale of millivolts, so there a lot of noise reduction necessary to achieve readable, accurate results **Criterion For Success** - Accurately transmitting full 12-lead EKG wave to a display at a reasonable frequency (hopefully ~ 20 samples per EKG grid box) -> could be limited to one bulb according to scope of the project - Successfully transmitting data without wires reliably (at least 1Mbps transmission rate) - Creating some kind of data visualization to display the wave on either screen or on a PC - Generating a bulb design that can successfully attach to the patient while housing all subsystem components while maintaining size constraint of being handheld (looking for palm sized or less) - Whole equipment should be “portable”, should be easily set up and transported - Easy to use, should ideally reduce amount of time required for a medical professional to take an EKG (hoping for less than 5-10 minutes end to end) |
