    FeetBeat: A Flexible Iontronic Sensing Wearable Detects Pedal Pulses and Muscular Activities

    The world-first pedal wearable system, named FeetBeat, has been presented to acquire both vital signals and muscular activities. This system has been seamlessly integrated into a shoe format by constructing a sensitive and flexible pressure sensing array enabled by the iontronic sensing principle. It can capture high-definition peripheral arterial pulse waveforms, from which heart rates and respiratory patterns can be extracted within a medical-standard precision. Meanwhile, the high spatial resolution of the sensing array not only allows alignment-free tracking of pulse signals, while serving as a location reference to identify individual pedal tendon activities, from which various foot gestures can be distinguished.

  • Novel Methods for Sensing Acoustical Emissions from the Knee for Wearable Joint Health Assessment

    We present the framework for wearable joint rehabilitation assessment following acute knee injury based on the measurement of acoustical emissions from the knee with miniature microphones. The research reported in this paper was highlighted in several major news pieces including Scientific American and BBC Radio.

  • Unobtrusive Sensing and Wearable Devices for Health Informatics

    The aging population, prevalence of chronic diseases, and outbreaks of infectious diseases are some of the major challenges of the present-day society. To address these unmet healthcare needs, especially for the early prediction and treatment of major diseases, health informatics which deals with the acquisition, transmission, processing, storage, retrieval, and use of health information has emerged as an active area of interdisciplinary research. In particular, acquisition of health-related information by unobtrusive sensing and wearable technologies is considered as a cornerstone in health informatics. Sensors can be weaved or integrated into clothing, accessories and the living environment.
