Conformal 2D/3D Wireless Modules Utilizing InkJet Printing and Nanotechnology

摘要

While batteries may be essential for reliable operation of applications requiring a more reliable and steadier supply, power scavenging techniques and zero-power nanostructure (e.g., CNT, graphene) based sensors can be reliably used for powering on a number of ubiquitous RFID and remote wireless sensing applications without the need for a battery, as shown in the prototypes presented in this article. By utilizing an optimized, selective metallization process such as inkjet printing, integrated 2D/3D battery-less power scavenging wireless sensing modules/ motes operating at frequencies well into the UHF range and beyond can be successfully fabricated in an environmentally friendly and cost-effective way for numerous applications including Internet of Things, Smart Skins, Smart WSNs and wearable biomoni-toring systems.
