Wearable and flexible sensors for user-interactive health-monitoring devices

Abstract

The development of flexible and wearable healthcare devices facilitates a real-time monitoring of body activities as well as detecting various biosignals, which provided useful information to manage one's health condition for personal health monitoring.

A Novel Strategy for Preparing Stretchable and Reliable Biphasic Liquid Metal

“…Stretchable conductive pattern, the foundation of flexible electronics, [1,2] demanding in concurrent of high conductivity, stretchability, long-term stability, and reliable mechanical performance, shows great potential applications in tactile electronics, [3,4] lithographic circuit, [5,6] soft bioelectronics, 3D printing of electrodes, [7,8] etc. In the previous study, a variety developing intrinsically stretchable conductive material compared to the pure metals, metal/elastomers (as described in Figure 1a), which possesses the advantage of both pure liquid and solid materials.…”

“…e) The conversion temperatures of both Ga 4 Ni 3 and InNi3 are detected. a) Schematic diagram of GaIn-Ni mixture structure: The interface between Ni particles and liquid GaIn exhibits incompatibility.…”

“…However, these materials with high Young's modulus possess poor stretchability and frangibility, and are prone to crack under stretching or bending environments, resulting in loss of electric conductivity. [15,16] Unlike these traditional conductive rigid materials, the emerging galliumbased liquid metals with advantages of low Young's moduli (1)(2)(3)(4)(5)(6)(7)(8)(9)(10) and in principle infinitely deformable have attracted great attention as an ideal candidate for fabricating stretchable conductive pattern. ), which is enabled to slightly elongate but it is also limited.…”

Parallel Signal Processing of a Wireless Pressure‐Sensing Platform Combined with Machine‐Learning‐Based Cognition, Inspired by the Human Somatosensory System

“…Electronic skin has been a rapidly advancing field of research over the past several decades. Electronic skin are devices that mimic the tactile sensing properties of human skin, which can be utilized in applications like wearable electronics, robotics, and prosthetics . Thus far, there have been numerous reports on different types and designs of tactile sensing (e.g., pressure and strain) electronic skin devices, which showed continuously improving performance over the years .…”
