Low-Cost Swine Health Monitoring: Chipless Resonant Sensors and RFID

Swine health monitoring using chipless resonant sensors and RFID technology is an innovative approach to monitoring the health of pigs. This technology allows for continuous, real-time monitoring of pigs' vital signs and other health indicators, which can help detect early signs of illness and prevent disease outbreaks. The Chipless resonant sensors are wireless sensors that do not require an integrated circuit or a power source. They operate using the principle of electromagnetic resonance, where a sensor's resonant frequency changes when it is in the presence of a specific target, such as a pig's vital signs. The sensors are easy to install and can be integrated into existing pig farming infrastructure, such as feeders and water spigot points. In this work, we have developed such low cost resonant sensors in the lab which are capable of reacting to a temperature change in the form of change in resonant frequency. These sensors are passive meaning they don't have any power source connected to them. The work also focused on the idea of using RFID tags as the traditional chip based sensors on pigs. These tags were experimented for identification of different pigs and to track the coarse motion of the proxy pigs in a laboratory environment. Various experiments were performed to determine the feasibility of using theses traditional chip based RFID tags. We also demonstrated the cost and performance limitations of the chip based as well as chipless sensors with respect to various conditions that we encounter in a pig farm.
