Design, Simulation and Measurement of Flexible PCB Coils for Wearable Device Wireless Power Transfer

A Study of Wearable Wireless Power Transfer Systems on the Human Body

“…4. The 26 locations were split into groups and categorized as either head (1-5), neck/bicep (6-10), arm (11)(12)(13)(14)(15), torso (16)(17)(18)(19)(20)(21), and leg (22)(23)(24)(25)(26). The torso category is the only group with 6 different locations due to its wide area of coverage compared to the other groups, which had 5 locations each.…”

“…For instance, in [24] only two body locations were simulated (without reporting any measured data) for a physically large WPT system, which is not suitable for wearable applications. Furthermore, studies such as the ones presented in [25] and [26], presented WPT systems with enhanced performance for wearable applications. However, neither measurements nor simulations of such systems were conducted on the human body.…”

“…The ANSYS human body model[31] with the placement and orientation of the CSCMR system on 26 different locations: (a) head (1-5), (b) neck/bicep (6-10), (c) torso (16-21), (d) arm(11)(12)(13)(14)(15), and (e) leg(22)(23)(24)(25)(26).…”

Recent Progress in the Preparation Technologies for Micro Metal Coils

“…Flexible sensors convert external deformation signals into electrical signals. MEMS sensors can achieve almost all sensory functions of the human body, including vision, hearing, taste, smell (such as the Honeywell electronic nose) and touch, which play an important role in health monitoring, motion monitoring, swallowing speech monitoring and intelligent rehabilitation [23][24][25][26][27][28][29]. With the development of micro coils, people can directly obtain certain body information in a convenient, fast, and friendly way.…”
