Large-area implementation and critical evaluation of the material and fabrication aspects of a thin-film thermoelectric generator based on aluminum-doped zinc oxide
Kirsi Tappura, Taneli Juntunen, Kaarle Jaakkola +4
A large-area thermoelectric generator (TEG) utilizing a folded thin-film concept is implemented and the performance evaluated for near room temperature applications having modest t…
Screen-printed and spray coated graphene-based RFID transponders
K. Jaakkola, V. Ermolov, P. G. Karagiannidis +7
We report Ultra-High-Frequency (UHF, 800MHz-1GHz) Radio Frequency Identification (RFID) transponders consisting of printed dipole antennas combined with RFID microchips. These are…
Near-Field UHF RFID Transponder with a Screen-Printed Graphene Antenna
Kaarle Jaakkola, Henrik Sandberg, Markku Lahti +1
As a method of producing RFID tags, printed graphene provides a low-cost and eco-friendly alternative to the etching of aluminum or copper. The high resistivity of graphene, howeve…
Exploitation of Transparent Conductive Oxides in the Implementation of a Window-Integrated Wireless Sensor Node
Kaarle Jaakkola, Kirsi Tappura
Exploitation of transparent conductive oxides (TCO) to implement an energy-autonomous sensor node for a wireless sensor network (WSN) is studied and a practical solution presented.…
A numerical study on the design trade-offs of a thin-film thermoelectric generator for large-area applications
Kirsi Tappura
Thin-film thermoelectric generators with a novel folding scheme are proposed for large-area, low energy-density applications. Both the electrical current and heat transfer are in t…
