There isn’t much open hardware medical instrumentation projects that can be considered completed and reliable. MobilECG project could pretend to be one that could compete with medical grade devices. Actually Péter, the founder of project, intended to collect decent amount of funding to get medical certification. But campaign didn’t went as planned, so he decided to make project open. Since the most of work is already done it would be sad to see project die. The decision to make it open is plausible and maybe it will completed with help of community.
MobilECG is very compact device that can measure ECG using 12 leads. The ECG signal is digitized using TI’s ADS1278 eight channel ADC. For interfacing and communication to host there are two AVR micros used – Attiny24 and ATU64. Schematic is developed using KiCAD software. Firmware isn’t complete – only minor functionality with several known bugs. Anyone with biomedical engineering knowledge will definitely see the potential of this device that can be attached to any device like PC, android or other and explore own ECG signals.
