Heart monitoring Design Partners also created the Viscero ECG vest, which uses electronic ink to monitor people’s heart rates. An abnormal heartbeat (arrhythmia)
can be life-threatening, leading to blood clots, stroke, heart failure and other complications. Therefore, it is essential that healthcare professionals accurately monitor patients’ heartbeats over an extended period (48 hours or more). But, the traditional Holter device used by the
majority of healthcare professionals is uncomfortable, and generally inhibits natural movement. This is not only an unpleasant experience for the wearer, but it can lead to inaccurate data, rendering it useless. Viscero is a medical-grade, six-lead
ECG monitoring system built into a t-shirt, that can be worn under clothes, unfelt and unnoticed. To collect accurate data, electrodes are positioned on the arms and waist under
compression points, which are specifically made using lamination to reinforce the fabric area. Te printed traces are connected to the main electronic “brain”, the size of a matchbox, that fits into a small pocket of the t-shirt. Tis makes it easy to remove for charging or when the t-shirt needs laundering. Te device links to a healthcare
professional’s dashboard, to be reviewed by a cardiologist when necessary, saving hours of trawling through ECG recordings.
