Fraun­ho­fer Insti­tut für Pho­to­ni­sche Mikro­sys­teme

Das Fraun­ho­fer-Insti­tut für Pho­to­ni­sche Mikro­sys­teme ist eines von 67 Insti­tu­ten der Fraun­ho­fer-Gesell­schaft, einer der füh­ren­den Orga­ni­sa­tio­nen für ange­wandte For­schung in Europa.

Bache­l­orthe­sis on the Cha­rac­te­riza­t­ion of Microf­lui­dic MEMS-Devices (IPMS-2018-129)

Work­ing field:

Flow-regu­la­tion and -gene­ra­tion on a micro­me­ter length scale are of high sci­en­ti­fic and indus­trial inte­rest in the ongo­ing trend of sys­tem minia­tu­riza­t­ion. The Fraun­ho­fer IPMS the­r­eby uses a paten­ted class of late­ral elec­tro­sta­tic ben­ding actua­tors to deve­lop a set of sili­con based Micro­pumps and Micro­val­ves devices. With the first pro­to­type devices being released from the in-house clean­room, the expe­ri­men­tal deter­mi­na­tion of per­for­mance para­me­ters of these devices pres­ents the aim of this work. The star­ting point is the fami­li­a­riza­t­ion of working with a microf­lui­dic cha­rac­te­riza­t­ion bench. With liquid volu­mes in the Nano-Liter range other mea­su­re­ment tech­ni­ques may be requi­red besi­des the usage of a stan­dard flow­me­ter.

Key aspects:

  • The deter­mi­na­tion of actua­tion-mode and fre­quency depen­dent flow-rate cur­ves
  • Cha­rac­te­riza­t­ion of the gene­ra­ted dif­fe­ren­tial pres­sure gene­ra­ted by the micro­pumps
  • Deter­mi­na­tion of the maxi­mum flowrate curve under the influ­ence of an impo­sed back­pres­sure
  • Elec­tri­cal Stan­dard Cha­rac­te­riza­t­ion of chip-devices
  • Deter­mi­na­tion of the ther­mo­dy­na­mic effi­ci­ency
  • Com­pa­ri­son of mea­su­red with ana­lyti­cal models and exis­ting simu­la­tion data.

Require­ments:

What you bring:

  • Basic know­ledge in the field of micro­sys­tems would be an advan­tage
  • Basic know­ledge in the field of fluid mecha­nics and / or microf­lui­dics would be an advan­tage
  • Basic know­ledge of working in a labo­ra­tory and know­ledge of metro­logy tech­ni­ques
  • Inde­pen­dent, goal-ori­en­ted and struc­tu­red way of working
  • Enjoy­ment of working in an inter­di­sci­pli­nary team

What we of­fer:

What you can expect:

You will find a large net­work of experts working in an open and col­le­gial envi­ron­ment wit­hin the excel­lent Fraun­ho­fer rese­arch and deve­lop­ment infra­struc­ture. We offer an excit­ing, up-to-date the­sis posi­tion in which you can bene­fit from our expe­ri­en­ced team. Our excel­lent indus­try-rela­ted rese­arch and deve­lop­ment infra­struc­ture pro­vi­des you access to a large net­work of experts. You will become part of an inspi­ra­tio­nal inter­na­tio­nal work envi­ron­ment based on trust, crea­ti­vity and team spi­rit. We bes­tow upon you the res­pon­si­bi­lity for your the­sis pro­ject, ensu­ring you space for auto­no­mous work.

Work is plan­ned to be car­ried out in our office in Cott­bus. The the­sis is awar­ded over a Ger­man part­ner uni­ver­sity accord­ing to the hig­her edu­ca­tion laws of the respec­tive federal state.

Fraun­ho­fer is Europe’s lar­gest app­li­ca­tion-ori­en­ted rese­arch orga­niza­t­ion. Our rese­arch efforts are gea­red ent­i­rely to people’s needs: health, secu­rity, com­mu­ni­ca­tion, energy and the envi­ron­ment. As a result, the work under­ta­ken by our rese­ar­chers and deve­l­o­pers has a signi­fi­cant impact on people’s lives. We are crea­tive. We shape tech­no­logy. We design pro­ducts. We improve methods and tech­ni­ques. We open up new vis­tas.
