Elucidating the Hemodynamic Origin of Ballistocardiographic Forces: Towards Improved Monitoring of Cardiovascular Health at Home
The ballistocardiogram (BCG), a signal describing the reaction forces of the body to cardiac ejection of blood, has recently gained interest in the research community as a potential tool for monitoring the mechanical aspects of cardiovascular health for patients at home and during normal activities of daily living.
Ballistocardiogram-Based Approach to Cuff-Less Blood Pressure Monitoring: Proof-of-Concept and Potential Challenges
We propose an ultra-convenient cuffless blood pressure (BP) monitoring approach based on the ballistocardiogram (BCG). The approach monitors BP using two mechanistically derived features in the whole-body, head-to-foot BCG: the time interval between the first and second major waves for DP, and the amplitude between the second and third major waves for pulse BP (PP; which can be added to DP to yield SP). The proposed approach can complement the conventional pulse transit time technique in two ways.
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.
