Chipless sensors are entirely passive devices whose electromagnetic signature is intelligible in time or frequency domain. The variations of the electromagnetic response of these devices can be used to sense environmental parameters at a very limited cost and with a minimum environmental impact. The most relevant configurations for designing environmental sensors are described and the main benefits and drawbacks of this technology are discussed.
