Textile-Based Capacitive Sensor for Physical Rehabilitation via Surface Topological Modification

5.4: A Textile Based Capacitive Pressure Sensor

INTRODUCTION The sense of touch plays an important role in everyday life. It provides the body with early contact to surrounding objects. By touching an object, we can tell if it is sharp or smooth; by holding it, we can estimate its weight. Skin is the most extended sensor of the entire human body. The haptic interface gives the first feedback to object manipulation; without sensing the pressu...

A Textile Based Capacitive Pressure Sensor

Background. As interest on wearable computing [1] increases, researchers are looking for new materials to use as a support for electronics. A fabric substrate is very appealing: it is elastic and extensible [2], supported by a well known technology and produced at low-cost. State of the art. Some smart pressure-sensors interfacing with a flexible substrate have been developed, but they are eith...

Couple Stress Effect on Micro/Nanocantilever-based Capacitive Gas Sensor

Micro/nanocantilevers have been employed as sensors in many applications including chemical and biosensing. Due to their high sensitivity and potential for scalability, miniature sensing systems are in wide use and will likely become more prevalent in micro/nano-electromechanical systems (M-NEMSs). This paper is mainly focused on the use of sensing systems that employ micro/nano-size cantilever...

Compliment Graphene Oxide Coating on Silk Fiber Surface via Electrostatic Force for Capacitive Humidity Sensor Applications

Cylindrical silk fiber (SF) was coated with Graphene oxide (GO) for capacitive humidity sensor applications. Negatively charged GO in the solution was attracted to the positively charged SF surface via electrostatic force without any help from adhesive intermediates. The magnitude of the positively charged SF surface was controlled through the static electricity charges created on the SF surfac...
