Han et al. are currently focusing on the design and manufacturing of wearable devices, and their applications to healthcare monitoring through a battery-free, wireless technology (i.e., Near Field Communications; NFC) [1-5]. Developing the system involves understanding diverse engineering fields, including materials science, structural design, circuit design, machine learning, augmented-reality (AR) system as well as clinical trials.
Battery-free, wireless, ionic liquid sensor arrays for patients in bed and wheelchair
Battery-free, wireless multi-modal sensor and actuator array system.
Real-time spatial mapping of pressure, shear, and temperature.
Automated system using wireless sensors and actuators during clinical trials.
Wireless, battery-free multi-axial sensor for augmented reality-assisted monitoring at skin interfaces
using machine learning.
A programmable, powerful, and ultra-fast sea cucumber inspired, water-driven self-operating soft actuator based on shape memory effect (SME) of PNIPAAm [6, 7].
Electrospun nanifber membranes for in vitro and in vivo biomedical applications that include cell culture platform [8], organ-on-a-chip [9], and tissue reconstruction [10].
Our research work includes design and manufacturing of micro/nano-scale structures and devices, and their applications to healthcare, flexible and wearable electronics, and reliability of micro/nano-scale structures and devices [11].
