Live demonstration: An ECG-on-Chip for wearable wireless sensors

We are demonstrating a wearable wireless ECG sensor prototype based on a highly integrated, ultra-low power ECG-on-Chip. The demonstration setup (as shown in Fig. 1) of the prototype sensor consists of 1) ST-Electromedicina ST-10 ECG signal generator 2) Prototype Sensor with the proposed ECG-on-Chip 3) Gateway application running in a notebook PC / Android smartphone. The signal output from the ECG generator is amplified, converted to digital domain and compressed by the ECG-on-Chip and streamed live via Bluetooth. The signal is received by a notebook PC with Bluetooth interface running the gateway application. The compressed signal is decompressed by the gateway application and displayed for observation/diagnostic purposes. This data can be uploaded to cloud server for long-term storage and more complex signal analysis. The signal transmitted by the sensor can also be received by a smartphone application in Android to visualize and analyze the signal further. A live subject will wear one of the sensors to demonstrate the ECG acquisition under normal daily activities like walking, running, jumping. ECG signals acquired during activities are shown in Fig 2.
