We develop a cardiac-and-piezoelectric hybrid system that can convert the contraction profiles of a cardiac tissue to electric signals for real-time and automatic detection.

We develop a dual-chamber microfluidic device to sequentially stimulate vasculogenesis and angiogenesis processes. This device enables vessel-tumor interactions for developing a vascularized tumor model.

We develop a microfluidic model system that can recaptulate the physiological environment of an artery to stimulate arteriogenesis on a chip and can develop a human arteriole model system for drug screening.

We develop a novel electrospinning process to create a piezoelectric microfiber sensor. This sensor is highly compliant and can attach to the skin of a muscle to monitor muscle activity. We have demonstrated that this muscle patch sensor can monitor muscle contractions and fatigue.

We develop a novel piezoelectric-microfiber sensor for swallow sensing. This sensor can be directly attached to the larynx area to monitor the hyoid bone and thyroid cartilage movements during the swallowing process. This sensor can be applied for the assessment of patients with swallow difficulty due to neuropathic diseases and aging.
