The idea behind RFID technology is similar to the one used for barcodes. However, it brings many advantages over barcodes since the information can be transmitted in a much longer range using a radiofrequency Tag.
The Tags are electronic labels, basically made with a microchip surrounded by a small antenna that can be activated by an electromagnetic field generated by a RFID Reader and can be rewritten many times.
RFID technology can apply to a wide variety of scenarios, i.e.:
- to monitor people and animals in medical or veterinarian environments (for example, the passive-tags used for pervasive temperature monitoring of people and objects);
- in the building industry, to measure concrete maturity, or to monitor humidity and corrosion of infrastructures;
- for precision farming and large retailers, to monitor cold chains of food and drugs;
- in logistics, to avoid collisions among lift trucks and operators;
- by shipping carriers, for shipment monitoring and tracking.
RADIO6ENSE, as technology developer, offers the following RFID sensors and systems:
T-Tags: Battery-less temperature tags, able to measure and wireless transmit the temperature of objects and their surrounding environment.
RFID TAGS (T-tags) are new generation wireless passive sensors used to pervasively measure temperature of people, objects, and environments.
WHAT DOES “PASSIVE SENSORS” MEAN?
A passive sensor is a battery-less tag activated by a radiofrequency reader that communicates with it through an electromagnetic field.
The Reader’s job is to activate the tag and to decode the signal received from it.
However T-Tag sensors work in both passive (no battery required) and battery-assisted (BAP) mode and we can customize them in size and shape.
They are suited to be placed over any kind of surface including metals and even the human body to collect body temperature.
Because of their low cost, T-Tags can be moreover used in applications wherein a large number of sensors is required.
For example, we have developed tags that can be mixed with concrete, or powders like soil, or sand, to measure deep temperatures.
SOME POSSIBLE T-TAGS APPLICATIONS:
1) Building Industry: T-Tag used to monitor buildings like houses, bridges, tunnels, and industrial plant.
2) Large-Scale Retail Trade and Pharmaceutical Industry: T-Tags are used to monitor the cold-chain in food and pharma. Inserted into pharmacy refrigerators or thermal bags, they can be used for long term monitoring of perishable food or in clinical studies.
3) Domotic systems: T-Tags integrated with modern domotic technologies, can be used to obtain a uniform air-conditioning, reducing energetic costs.
4) Human Body Temperature monitoring: t-tags can also be used for wireless measures of human body temperature.
5) In healthcare applications, for example, T-Tags may support the optimization of clinic procedures and improve patients and operators safety.
