Proceedings ArticleDOI
Advances in implantable and wearable antennas for wireless brain-machine interface systems
Elham Moradi,Karoliina Koski,Toni Bjorninen,Rikky Muller,Peter Ledochowitsch,Lauri Sydanheimo,Elad Alon,Michel M. Maharbiz,Jan M. Rabaey,Leena Ukkonen,Yahya Rahmat-Samii +10 more
TL;DR: Wirelessly addressable battery-free implants are a must to convert thought into action and sensation into perception and there can be no transcranial feedthrough for wires or batteries which require replacement.
Proceedings ArticleDOI
Circularly Polarized Textile Tag Antenna for Wearable Passive UHF RFID Systems
TL;DR: In this article, a circularly polarized tag antenna using textile materials for wearable passive ultra high frequency (UHF) radio frequency identification (RFID) system was presented, which achieved best axial ratio values of 2.1 dB and 2.2 dB for both in air and on-body conditions, and desirable corresponding read range of 9.1 m and 8.4 m.
Proceedings Article
Charge Storage Level Sensor RFID Tag: Impedance Matching and Experimental Characterisation
TL;DR: An RF energy harvesting system where two distinct passive UHF RFID microchips provide different tag IDs to detect low and high states of the harvester’s charge storage enables the backend system to acknowledge when the harvesting system is ready for advanced power consuming operations.
Proceedings ArticleDOI
Wearable and implantable antennas for wireless body-centric sensing systems
Toni Bjorninen,Elham Moradi,Karoliina Koski,Lauri Sydanheimo,Leena Ukkonen,Rikky Muller,Peter Ledochowitsch,Jan M. Rabaey,Yahya Rahmat-Samii +8 more
TL;DR: In this poster abstract, recent advances on implantable and wearable antennas for wireless body-centric sensing systems are presented and more detailed simulation and measurement results are presented.
Proceedings ArticleDOI
Dual-ID Headgear UHF RFID Tag with Broadside and End-Fire Patterns based on Quasi-Yagi Antenna
TL;DR: In this paper, a quasi-Yagi antenna on a periodic surface for a dual-ID passive UHF RFID tag embedded in headgear is presented, which produces a near end-fire radiation pattern directed towards the user's line of sight with the directivity of 4 dBi.
