Wearable multifunctional printed graphene sensors

Abstract

Versatile and wearable graphene sensors Printed laser induced graphene (LIG) enables versatile multiple-parameter piezoresistive sensing in actual fields. An international team led by Prof Jurgen Kosel from King Abdullah University of Science and Technology, Saudi Arabia develops bending piezoresistive sensors based on laser induced graphene (LIG) on flexible polyimide substrate to accurately detect curvature, force, deflection and flow. When combined with double-sided device design to complete compensate the temperature effect and commercial ultra-low power aquatic tags, the LIG sensors can be used for various marine life measurements and monitoring, such as marine animals’ speed monitoring under realistic and harsh conditions. These LIG sensors presented here fulfill several key requirements such as low cost, light weight, flexibility and minimal intrusiveness and are thus promising for future applications in wearable electronics.
