Novel Passive Rfid Temperature Sensors Using Liquid Crystal Elastomers, Yousuf Shafiq Mar 2020

Novel Passive Rfid Temperature Sensors Using Liquid Crystal Elastomers, Yousuf Shafiq

FIU Electronic Theses and Dissertations

When transporting perishable foods in the Cold Supply Chain (CSC), it is essential that they are maintained in a controlled temperature environment (typically from -1° to 10°C) to minimize spoilage. Fresh-food products, such as, meats, fruits, and vegetables, experience discoloration and loss of nutrients when exposed to high-temperatures. Also, medicines, such as, insulin and vaccines, can lose potency if they are not maintained at the appropriate temperatures. Consequently, the CSC is critical to the growth of global trade and to the worldwide availability of food and health supplies; especially, when considering that the retail food market consists mostly (approximately 65%) …


Structural Health Monitoring Inside Concrete And Grout Using The Wireless Identification And Sensing Platform (Wisp), Elicek Delgado Cepero Mar 2013

Structural Health Monitoring Inside Concrete And Grout Using The Wireless Identification And Sensing Platform (Wisp), Elicek Delgado Cepero

FIU Electronic Theses and Dissertations

This research investigates the implementation of battery-less RFID sensing platforms inside lossy media, such as, concrete and grout. Both concrete and novel grouts can be used for nuclear plant decommissioning as part of the U.S. Department of Energy’s (DOE’s) cleanup projects. Our research examines the following: (1) material characterization, (2) analytical modeling of transmission and propagation losses inside lossy media, (3) maximum operational range of RFID wireless sensors embedded inside concrete and grout, and (4) best positioning of antennas for achieving longer communication range between RFID antennas and wireless sensors. Our research uses the battery-less Wireless Identification and Sensing Platform …
