Special Issue Information

Dear Colleagues, 

Wearable technologies have gained significant research and market traction in recent years. Wearables are often empowered with wireless communication, wireless powering, smartphone connectivity, and GPS/WiFi tracing functions. Integration with multi-function physical and biochemical sensors advances wearable applications in healthcare, fitness, therapy, senior and infant care, security, and safety, along with the features of convenience, comfort, and ubiquitousness. The noninvasive sensing of physical and biochemical parameters is essential for practical applications. New research and inventions utilizing electrical, optical, magnetic, acoustic, and thermal sensing modalities have been explored along with considerations for low-power, high-speed and flexible electronics, on-body or in-body antennas, and electromagnetic environments and interference. This Special Issue focuses on state-of-the-art non-invasive sensing technologies, particularly for wearables and their applications.

This Special Issue welcomes research works on electrical, optical, magnetic, acoustic, and thermal sensing modalities, as well as the electronic device and system designs using these modalities for wearable applications. The scope includes, but is not limited to, ECG (electrocardiography), EEG (electroencephalography), EMG (electromyography), skin impedance spectroscopy, photoplethysmography, IR (infrared) and NIR (near infrared), microwave, millimeter-wave, radio-frequency, ultrasound, nuclear magnetic resonance, and fluorescence sensing. Manuscripts should include targeted wearable applications and methods about how the proposed sensing mechanisms can be used in wearables. Sensing modality studies that do not include convincing evidence or potential electronic designs for wearable applications are not within the scope of this Special Issue. Manuscripts related to signal and data processing techniques as well as machine learning methods for noninvasive sensing are welcome, but need to include experimental results as validation. Manuscripts with experiments conducted on human bodies should include an approved study protocol statement.

Wearable medical devices (WMDs) for healthcare applications have become ubiquitous, allowing remote, at-home, and real-time chronic monitoring that have significantly decongested clinics. These WMDs permitted the monitoring of several physiological parameters, such as heart and respiration rates, SPO2, temperature, and energy expenditure during activities of daily living (ADLs) or fitness activities. While the measurement of these parameters has become common, full noninvasive, unobtrusive, and real-time blood pressure (BP) monitoring remains elusive owing to BP’s complex dynamics. To bring this into fruition, several works have been conducted combining different biosignals to indirectly extract BP by using PTT. Unlike previous works, we considered PTT variability by averaging it over discrete durations to account for BP variability for a more accurate estimation. PTTs were obtained using electrocardiograph (ECG) and reflective photoplethysmograph (rPPG) signals extracted by a wearable device attached to a single site on the upper arm. Our results show a significant correlation between average PTT and the BP measured using auscultation in a trial study. The developed system has potential for chronic, noninvasive, and cuff-less blood pressure monitors (BPMs) for localized and single-site implementations. Meanwhile, real-time data from the wearable device may be accessed via a remote desktop or a mobile phone application. Full article
