Student Design Competition

WPT2016 Student Design Contest (WPT2016_SDC)

Introduction:

The WPTC2016 will, for the first time, introduce a SDC (Student Design Contest), opened to all students, from undergraduate to PhD level. The goal of this SDC is to design, build and demonstrate a functioning wireless energy harvester. Each team is responsible for building the system and bringing it to the conference for measurement and evaluation. Specific design considerations and evaluation criteria is presented further.

 

Eligibility criteria:

  • At least one of the team members must register for and attend the conference to present their design for evaluation at the specified time and location (Congress Center)[1].
  • Students may enter as individuals or as a team. There may be no more than three students on a team.

How to participate:

  • The students willing to participate should send an email to mtts.aveiro@ieee.org by March 30. The e-mail should have the subject “WPTC2016 SDC” and contain the constituting elements of the team and a signed statement from their academic advisor that the work is principally the effort of the student(s).

Design considerations:

  • The frequency of operation of the system is to be chosen by each team within the interval from 0.5 GHz and 6 GHz.
  • The output power level of the source is also selectable by each group up to a maximum of 1 W EIRP.
  • The full design must fit inside a 30x30x30 cm box.
  • The full design must not weight above 500 g.
  • The designs must supply DC power to a resistive load. This resistive load is selected, and provided, by the competing teams and must be detachable from the harvester circuit to be measured (using a standard multimeter). The size and weight of the design will be evaluated without this DC load.
  • The design cannot include any power sources (batteries, solar panels, etc.) and must be viable for visual inspections of the constituting elements.
  • Each team can bring different prototypes for testing. However, only one design will be evaluated for each team. Moreover, each team will have a limited time to conduct their tests prior to the evaluation by the judges. Keep this in mind when deciding how many prototypes to bring for the contest.

Measurement and evaluation criteria:

  • The designs will be measured for output DC voltage using a standard multimeter:
    • The measurement will take place within a nearly EM isolated environment.
    • The design will be placed in a support facing the transmitting antenna at a distance of 4 meters.
    • The position of the design can be adjusted by the competing team, within a designated area.
  • The design is also measured in size:
    • The size of the design is considered to be the smallest rectangular box in which it fits.
  • The design will also be weighted.
  • The winners will be the team which achieves the highest FOM (Figure of Merit), according to the following criteria:

WPTC2016_SDC_Formula

Where:

is the output DC power provided by the harvester in watts (W)

is the EIR power of the transmitting source in watts (W)

is the weight of the harvester in grams (g)

is the volume of the smallest rectangular box within which the harvester can fit in cubic centimeters (cm3)

Prizes:

  • The winner of the WPTC2016 SDC will be rewarded with a 500€ prize offered by the sponsoring company CST.

 

The student design competition is to be held on Thursday, 5 of May 2016, as part of the WPTC2016, and will be held within the premises of the conference venue.

The Wireless Power Transfer Conference 2016 Student Design Contest is organized by the MTT-S Student Branch of the University of Aveiro and is sponsored by CST (Computer Simulation Technology).
