Interests: wearable electronics; implantable electronics; nanoengineering and bioengineering
Soft, functional materials enable comfortable, low-profile electronic systems, including sensors, stimulators, and actuators, for applications in medicine, healthcare, and human–machine interfaces. Engineering of materials that provide a very small form factor when integrated with functional components makes extremely flexible and stretchable electronics, which can overcome the current limitations of existing electronics based on rigid, planar materials. In addition, soft electronics-enabled biosystems offer compliant, ergonomic interactions and tissue-conformal lamination with a human body for highly sensitive detection of physiological signals.
This Special Issue focuses on the use of soft, hybrid, functional materials to design and develop unobtrusive, multifunctional wearable and implantable electronics for biomedical applications. Specifically, we seek papers that discuss new soft materials, flexible/stretchable sensors, and soft actuators to advance fundamental knowledge or technology in human health monitoring, disease diagnostics, healthcare, brain–computer interactions, and human–machine interfaces.
We invite full papers, communications, and reviews that cover one or several of the listed keywords below.

Title: Development of textile capacitive pressure sensing insole for gait pattern analysis in healthy adults and patients with hemiparesis
Abstract: The purpose of this study was to develop a textile capacitive pressure sensing insole (TCPSI) and a real-time monitoring system for gait pattern analysis in healthy adults and hemiparetic patients. In this paper, two separate experiments were carried out. Performance evaluation of the developed insole sensor was first executed by comparing the signal accuracy level between TCPSI and F-scan. Gait data from 15 healthy subjects were simultaneously collected by both sensors for 3 minutes on a treadmill at a fixed speed. Each participant walked for four times at the speed of 1.5 km/h, 2.5 km/h, 3.5 km/h, and 4.5 km/h, where the gait speed was randomly chosen. Step count data from both sensors resulted in 100% correlation in all of the four pre-defined gait speed conditions (1.5 km/h: 89±7.4, 2.5 km/h: 113±6.24, 3.5 km/h: 141±9.74, 4.5 km/h: 163±7.38 steps). Stride time was concurrently determined by the two sensors, and the results showed an average of 90.1% correlation in the left foot, and 89.7% correlation in the right foot (p<0.05). Bilateral gait coordination analysis was secondly performed in healthy adults and hemiparetic patients to examine the feasibility of the developed sensor with the monitoring system for future clinical and normative studies. For this experiment, a total of 34 subjects (n=17; hemiparetic) participated and phase coordination index (PCI) was used for analysis. PCI value of the healthy subjects resulted in 5.62% (SD±5.05%) and hemiparetic patients had 19.5% (SD±13.86%). The results showed a threefold difference between the two groups; these results conform to those of previous studies. Therefore, the insole developed in this study has been confirmed to have an equivalent performance to commercial sensors, and thus can be used not only for future sensor-based monitoring device development studies but also in clinical setting for patient gait evaluations.
