Flexible conductive polymer composites for smart wearable strain sensors

Abstract

Wearable strain sensors based on flexible conductive polymer composites (FCPCs) have attracted great attention due to their applications in the fields of human-machine interaction, disease diagnostics, human motion detection, and soft robotic skin. In recent decades, FCPC-based strain sensors with high stretchability and sensitivity, short response time, and excellent stability have been developed, which are expected to be more versatile and intelligent. Smart strain sensors are required to provide wearable comfort, such as breathability, selfcooling ability, and so forth. To adapt to the harsh environment, wearable strain sensors should also be highly adaptive to protect the skin and the sensor itself. In addition, portable power supply system, multisite sensing capability, and multifunctionality are crucial for the next generation of FCPC-based strain sensor.

Functionalization of Low‐k Polyimide Gate Dielectrics with Self‐Assembly Monolayer Toward High‐Performance Organic Field‐Effect Transistors and Circuits

“…As one of the most important electronic devices, organic field-effect transistors (OFETs) have broad application prospects in flexible electronics, information storage, biomedical fields, and large-area flat-panel and flexible displays. [1][2][3][4][5][6][7][8][9] An important premise of the application implementation mentioned above is to use organic integrated circuits (ICs) as the hub, which requires the dielectric materials with low dielectric constant (ε). The reason could be explained that the leakage current, parasitic capacitance, circuit dissipation, resistance-capacitance delay, circuit heating issue, and cross-talk line noise in organic ICs could be effectively reduced by using low-k dielectric materials.…”

“…This vulnerability exacerbates the instability of electrical signal output, especially in applications such as biochemical sensor that require humid environments. To overcome these concerns, a series of optimization methods have been innovated, such as the design and synthesis of solution‐resistant polymer semiconductor materials, 11–14 the introduction of protective structures on FETs, 15,16 and the construction of epitaxial grids 17,18 . While these methods prevent the interference of external forces on electrical signals to some extent, they typically suffer from complicated preparation steps, expensive processing techniques, and the degeneration of device performance 19 …”
