Fabrication Technologies for Flexible Printed Sensors

Printing technologies are a convenient enabler for the rapid and cost-efficient prototyping as well as for the manufacturing of flexible sensors, which can be integrated in different types of materials and wearables. At the same time printing is considered to have a low environmental impact, provided that sustainable materials are used. As part of this article, a systematic review of different printing technologies for printed electronics applications is provided, including the basic working principles, the achievable resolutions and processing speeds, specific challenges, processable materials, as well as focusing on the usage for the fabrication of flexible sensors and sensor systems.
