Sažetak
The standardisation of short-range wireless radio protocols such as Bluetooth, ZigBee, WiFi and radio frequency identification (RFID) is opening new markets for distributed sensors and sensor networks. The fusion of chemical and biosensor technologies with these various short-range, low-cost, wireless technologies is creating new opportunities for ubiquitous chemical and biological sensor systems in healthcare, environmental monitoring, process and quality control, and chemical and biological threat detection. In this work we present a radio frequency (RF) sensor tag for use as a distributed smart chemical and biological detector, based on the RFID platform. The tag has a planar 4-point gold electrode (conductometric) interface onto which a chemically or biologically sensitive film is immobilised using planar fabrication techniques. The conductometric measurement is controlled and sampled by on-tag electronics, which then communicates the (bio)chemical information wirelessly over the RF link. The low-cost sensor tag is suitable for use in distributed, ubiquitous and pervasive wireless data applications and sensor networks. We envisage a diverse range of deployment scenarios for the sensor tag, including short-term mobile applications, such as wearable sensors for chemical and biological exposure and contamination monitoring and smart personal diagnostics, to longer-term in-situ applications such as in-building environment monitoring and structural integrity maintenance.
