Self-powered wearable sensors devices can not only increase adoption and compliance but also enable long-term and continuous monitoring of many key health and environmental parameters. In order to achieve self-powered operation, it is essential to maximize the power generated from the body and minimize the power consumed by sensors, computation, communication and power management to achieve the self-powered operation. Recent advances in nanomaterials, nanostructures, and nanodevices have increased efficiency of energy harvesters, lowered energy per computational bit, increased capacitor storage density, and enhanced nanosensor efficiency making autonomous operation realizable. In this talk, I will discuss how these advances are being combined together to build self-powered wearable sensor systems, which can enable long-term sensing and effective management of chronic conditions, sensing of personal exposure to air pollutants and toxins and provide longitudinal studies that can provide new insight into correlation of various health and environmental parameters. I will also discuss the role that data will play in making these systems effective for both the patient and the provider.
