Mission!
RADIO6ENSE is a spin-‐off of the University of Roma "Tor Vergata", aiming at developing short-‐range distributed RFID sensing technology to discreetly measure and quanAfy our interacAon with things and with the surrounding spaces. RADIO6ENSE's products and services provide the last 10 meters of the emerging Internet of Things, enabling Cloud Services to interact with the real World. RADIO6ENSE offers hardware and soIware soluAons addressed to System Integrators, Engineers, Consultancy companies, Public and Private Agencies, as well as End Users willing to introduce the RFID Sensing Technology inside their own processes and work-‐flows.

• The Wearable Tags are passive UHF RFID tags suitable to operate in close proximity of the human body.
• The lightweight materials and the small sizes allow them to be placed in
ü badge necklace ü wallets ü pockets or pursues ü Smart plasters, wristbands, clothes, sport suits and
garments in general.
• On request, RADIO6ENSE is available to customize the size, material and the shape of the wearable tags according to the specific applicaAons.
Wearable RF Tags
Tags of different sizes and shapes produced by radio6ense can achieve up to 6 meters read range enabling a robust monitoring in a 4x4 m room with a single reader.
