We present a low power, miniaturized biomedical sensor node featuring electro-, seismo-and gyrocardiography. Measurement session can be set up and controlled over Bluetooth Low Energy interface. Acquired raw or preprocessed sensor data can be stored locally to the microSD memory card. To the best of the authors' knowledge, the presented device is the smallest reported to enable heart monitoring from the electrical and mechanical (with six degrees of freedom) viewpoint. The average power consumption of the device is less than 15mW, enabling continuous acquisition of high quality data of more than 60 hours with the used 250mAh Lithium-Polymer battery.
