Towards Ubiquitous Blood Pressure Monitoring via Pulse Transit Time: Theory and Practice
Ubiquitous blood pressure monitoring is on the horizon for two reasons. One reason is a profound need. Hypertension is a major cardiovascular risk factor that is treatable, yet high blood pressure detection and control rates are abysmally low, especially in... Read more

Ballistocardiogram-Based Approach to Cuff-Less Blood Pressure Monitoring: Proof-of-Concept and Potential Challenges
The goal of this study was to propose and establish the proof-of-concept of an ultra-convenient cuffless blood pressure (BP) monitoring approach based on the ballistocardiogram (BCG).  The proposed approach monitors systolic and diastolic BP (SP and DP) independently by exploiting... Read more

Guide-wired Helical Microrobot for Percutaneous Revascularization in Chronic Total Occlusion in-vivo Validation
Here we show an enhanced powered guide wired helical millirobot for mechanical thrombectomy in cardiovascular intervention capable of autonomous therapeutics. We build up and demonstrate a millimeter robot fabrication with a spherical joint and a guidewire, a high-power and frequency actuation via external electromagnetic field control, and autonomous therapeutic motions comprise driving, steering, and drilling. We validate all performances in two-dimensional fluidic channels mimicking the vascular network and finally in-vivo environments. Beyond nature-inspired millirobot technologies, our work has the potential of advanced mechanical thrombectomy application and advancement of micrometer and millimeter robot technology toward real clinical utilization...
