PCard - Personal Cardiac monitor

PCard is an innovation in mobile monitoring of vital physiological health-state parameters and the context of the user’s environment. The system is based on a small body sensor (BS), which enables the measurement of ECG, EMG, EEG, temperature, heart and respiratory rates, motion and acceleration. The BS is wirelessly connected to a personal mobile unit (smartphone) that communicates with it and processes, analyzes and displays measurements. The mobile unit is connected, via Internet, to a secure server where the measurements are stored and, if necessary, further processed. The BS is a small, user-friendly and unobtrusive device, suitable also for older people, patients, children, athletes and people with special needs.

A commercial version of the medically certified ECG sensor – trademarked SAVVY ECG www.savvy.si – is available on the market since 2016. The transformation of knowladge from JSI to the private sector (Saving, d.o.o. and L-TEK, d.o.o.) was awarded with the Puh Certificate of Recognition for significant achievements in the field of medical equipment in 2017. The device has been sold internationally and has since been used by the general public, by individual medical professionals, and by medical institutions.

ECG analysis software that can deal with intermittent signals.
ECG analysis software that can deal with intermittent signals.

The device in its current design is a result of almost a decade of research, development, testing and upgrades. It started before smartphones as we know them today were available and before the Bluetooth Low Power standard made its way into consumer electronics. Currently, body sensor can be connected to modern Android smartphones and tablets, to PCs running Linux, to single-board computers, such as the Raspberry Pi, and even to embedded devices with Bluetooth 4 or later. To use it to its full potential, however, Internet connection on the connected device is a necessity. Large measurements that span multiple days can be most efficiently stored and processed in the Cloud.
