Highly stretchable and conformal bioinspired kirigami structural epidermal electrodes for ECG recording during daily activities (opens in new tab)

The conformal adaptation of epidermal electrodes to the skin is crucial for achieving stable electrocardiogram (ECG) signal monitoring during exercise. Here, we present a bioinspired kirigami-structured epidermal electrode (BKSEE) specifically designed for dynamic human–machine interfaces. The BKSEE consists of three distinct layers: a copper electrode featuring a bioinspired kirigami structure (BKS), an adhesive film made of polyethylene glycol (PEG) and polydimethylsiloxane (PDMS), and a PD...
