Abstract
Continuous and precise monitoring of physiological signals via epidermal sensors could be of use in the development of personalized healthcare. However, the practical deployment of such sensors is hindered by the need for bulky batteries and limitations in data transfer. Here we report a battery-free epidermal network that is wirelessly interconnected through a wearable metamaterial and can provide continuous, high-fidelity biosensing. The network separates the power transfer (13.56 MHz) and data communication (2.4 GHz) channels through a dual-mode metamaterial textile, providing efficient wireless power transfer and low-latency data communication. We use a smartphone as a hub to wirelessly deliver power to and acquire biological signals from multiple networked epidermal sensors mediated by the metamaterial, which is integrated in clothing. The network can continuously monitor systolic blood pressure, including in dynamic environments such as during exercise.
