Material Approaches to Stretchable Strain Sensors

ChemPhysChem, 2015
AbstractWith the recent progress made in wearable electronics, devices now require high flexibility and stretchability up to large strain levels (typically larger than 30 % strain). Wearable strain sensors or deformable strain sensors have been gaining increasing research interest because of the rapid development of electronic skins and robotics and ...

Carbon nanotube yarn strain sensors

Nanotechnology, 2010
Carbon nanotube (CNT) based sensors are often fabricated by dispersing CNTs into different types of polymer. In this paper, a prototype carbon nanotube (CNT) yarn strain sensor with excellent repeatability and stability for in situ structural health monitoring was developed.

Effects of the textile-sensor interface on stitched strain sensor performance

Proceedings of the 23rd International Symposium on Wearable Computers, 2019
The influence of the textile substrate on the performance of a textile-based strain sensor has not been well understood or characterized in many wearable sensor evaluations. The underlying textile has its own anisotropic mechanical behaviors due to its woven or knit fabrication process, and introduces non-trivial structural influences on integrated ...

Stretchable Encapsulation for Implantable Strain Sensors

ACS Applied Materials & Interfaces
Implantable strain sensors integrated on organ surfaces can monitor organ deformations, such as bladder filling and stomach motility, thereby providing important information about their functional states. A major challenge lies in achieving large strain ranges while ensuring biocompatibility and long-term stability inside physiological fluid ...

Strain sensor using twisted optical fibers

Optics Letters, 1984
A novel sensor using twisted optical fibers is proposed to detect distributed tensile strain. This sensor converts tensile strain to optical loss. The relation between tensile strain and optical loss is modeled and experimentally confirmed for uniform tensile strain.

Coatable strain sensors for nonplanar surfaces

Nanoscale
A versatile coatable strain (CS) sensor was developed using a wet process, achieving a high sensitivity (GF ≈ 100). It overcame traditional polymer limitations, enabling real-time growth measurements on complex biological and non-planar surfaces.

EVALUATING STRAIN SENSOR PERFORMANCE FOR MOTION ANALYSIS

Proceedings of the International Conference on Biomedical Electronics and Devices, 2011
Investigation on the more suitable technologies to register human body movements in 3D space with great spatial accuracy is a very challenging task, because a wide range of applications are concerned, from registration of post-stroke rehabilitation or sports performance, to monitoring of movement of disabled or elderly people, etc.

SAW OFC strain sensor

2009 IEEE International Ultrasonics Symposium, 2009
This paper presents results for a 250MHZ orthogonal frequency coded (OFC) surface acoustic wave (SAW) cantilever device on YZ LiNbO 3 . A 1-D model is presented which predicts the variation in the wave velocity with applied strain. A FEM analysis is conducted which verifies the strain on the cantilever and supports the 1-D model predictions.
