Garment ECG system with hitoe® dry electrode.
A, The hitoe® dry electrode is sewn into a stretchy fabric used for sportswear, for a wearable ECG unit that can be washed. The unit can be put on and taken off easily by patients, facilitating near-continuous monitoring. B, The hitoe Medical Leads II: Lead wires are pre-installed on the wearable device and conduct the signal detected by the electrodes to the electrocardiograph. The pressure adjustment function allows the wearer to obtain the proper position and adherence, enabling comfortable extended monitoring. C, The hitoe Medical Electrode II: Electrodes are made of an electrically conductive textile material called hitoe. The polyester nanofiber fabric is coated with a dielectric polymer to prevent rash even with prolonged use. D, The hitoe ECG Recorder EV-301: The recorder is a compact lightweight Holter electrocardiograph, capable of continuous recording for up to 2 weeks without recharging. ECG, electrocardiogram.
