Wearable and Battery-Free Health-Monitoring Devices With Optical Power Transfer

Nattakarn Wuthibenjaphonchai et al.

Summary: Wireless epidermal wearable devices are gaining interest as a personalized, low-cost health monitoring technology, especially when combined with biosensors. The implementation of a battery-free approach has successfully extended the device's lifetime and reduced its volume, resulting in a wireless power system and painless measuring system. The device, exemplified by a glucose sensor for diabetes monitoring, utilizes energy harvesting technology and noninvasive sensors to achieve optimal functionality for a variety of glucose concentrations.

Textile Chipless Tag for Gesture Recognition

Giuseppina Monti et al.

Summary: This paper presents a novel fully-textile chipless tag for gesture recognition applications, in which the transmission zeros are controlled by the position of the fingers. A three-finger prototype using non woven conductive fabric is shown to be suitable for integration into a glove, demonstrating the feasibility of using the proposed tag for gesture recognition applications.

Microwave Wearable System for Sensing Skin Hydration

Raissa Schiavoni et al.

Summary: This paper discusses the implementation of an innovative wearable device for monitoring skin hydration through microwave reflectometry technique. The study involved experimental validation and full-wave simulations on human phantoms to establish the relationship between skin dielectric permittivity and the monitoring system's frequency response. The results suggest that the system has the potential for real-time, continuous monitoring of skin hydration.
