摘要

This study presents two prototypes of an innovative design idea, referred to as thern"Electronic Mosquito". The Electronic Mosquito (or "e-MosquitoTM") is a MEMS-basedrndevice that resembles the blood-extracting action of a mosquito. At a miniature scale, thernproposed system provides controlled sequential actuation of and array of microneedlesrnthat penetrate the skin to sample a very small static blood droplet for further analysis. Thernactuation of an individual microneedle is of crucial importance for the appropriaternoperation of the e-MosquitoTM device. Hence, to test the feasibility of the proposed e-rnMosquitoTM concept, two different MEMS prototypes were implemented using standardrnmicromachining techniques. Initially, a chip was manufactured using Multi User MEMSrnProcesses (MUMPs?) technology. The prototype contains a number of electrostaticallyrnactuated microbridges, some of which with an additional centrally mounted mass tornsimulate the weight of the microneedle. Secondly, Silicon-on-Insulator (SOI)-based highrnaspect-ratio technology (MicraGEM?) was applied to compare thermal and electrostaticrnmicroactuators. The thermal microactuators were displaced up to 44um and have beenrnfound to be more suitable for the e-MosquitoTM application. Thirdly, utilizing the samernSOI-based technology, a variety of thermally actuated microneedles were implementedrnfor the purpose of testing their integration and dynamic behavior while being actuated.rnThese microneedles were effectively actuated resulting in a displacement of up to 20um.
