Project activities started with a thorough analysis of the competing technological solutions available in the sensor market. The electromagnetic characterization of candidate materials (graphene, carbon nanotubes, polymers) able to sense changes in some environmental parameters (temperature, humidity, stress, gas ) have been performed as well. Within this framework, a selection of the materials having the best sensitivity to the parameters to sense has been considered for the integration in sensors. Analysis and characterization of the conductive inks in terms of surface conductivity has been also addressed and low-cost solutions have been found. Inkjet printing on polyimide and coated papers have been performed.
OVERVIEW OF THE RESULTS (final period):
The main objective of this work package has been to show operation of the prototypes in realistic scenes before they can be taken into account to be included in real applications and become a mature and reliable technology in the near future. The performance of three final prototypes integrating the work done during the project. Two of them are based on chipless RFID sensors and the last one based on semi-passive RFID sensor:
- Temperature sensor. The validation of a novel chipless temperature threshold sensor structure in a real environment is done. Two structures based on a C-scatterer are proposed.
- Permittivity sensor. A permittivity sensing prototype based on depolarizing tags using dedicated reader is reported.
- Apnoea detector. A wireless apnoea detector using a semi-passive RFID tag is presented. The device is based on the measurement of the airflow temperature changes that are produced during breathing.
EXPLOITATION AND DISSEMINATION (final period):
- Activities related to communication and outreach of project progress and results planned have been accomplished.
- Many networking events, those planned and new ones, have been attended by the project’s partners.
- Several journal papers have been published with the acknowledgment to the EMERGENT project. - Several publications appeared also in international conferences. The complete list of publications is available on the portal and on the EMERGENT website. The open access version of the paper is available on the project website.
- EMERGENT website (
http://www.emergent-rise.eu(se abrirá en una nueva ventana)) has disseminated project progress results and promoted project events also through the Twitter account of the Project (@emergent_rise).
- An article entitled 'From sensors to readers' has been published at page 96 on “Platinum online Journal, section Research&Innovation”, an international insert of the “Sole24ore” Newspaper.
- An animation video, developed with a professional company, has been has been posted on the project website and also on the Social Networks (Twitter, Facebook).
