With this material system, we created vivid, free-floating structural colored microparticles with magnetic rotational control for multiplexed bioassays. Also we developed polymeric nanocomposite microactuators undergoing predesigned and complex motions capable of utilizing in various microsystems, by programming heterogeneous magnetic anisotropy. We envision that confining self-assembled nanparticles in polymer provides a new methodology to program advanced properties for the development of functional polymeric microstructure.","PeriodicalId":202479,"journal":{"name":"2013 Transducers & Eurosensors XXVII: The 17th International Conference on Solid-State Sensors, Actuators and Microsystems (TRANSDUCERS & EUROSENSORS XXVII)","volume":"423 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122725321","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We present a refreshable tactile system based on the opto-mechanical properties of liquid-crystalline elastomers (LCE) composites, with the capability to represent Braille characters and graphic information. The actuators designed are based on the stress gradient generated in the elastomer under illumination to exert a force on movable components.

It is well known that physical parameters, such as jet velocity and jet diameter determine the penetration characteristics of liquid micro-jets into a specific tissue [1]. The optimum injection parameters vary significantly for different types of tissues. Therefore, we have used high speed video monitoring and force sensor measurements to characterize the liquid jet. The penetration into the tissue is then analyzed by Optical Coherence Tomography (OCT) [2]. This enables the general description of the specific jet's physical properties as well as the penetration characteristics with respect to a specific tissue. In the experimental study, jets with diameters of 100 μm and jet lengths from 6 to 18 ms (~ 2 to 9 μl) have been injected into colon tissue from pigs.","PeriodicalId":202479,"journal":{"name":"2013 Transducers & Eurosensors XXVII: The 17th International Conference on Solid-State Sensors, Actuators and Microsystems (TRANSDUCERS & EUROSENSORS XXVII)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122217174","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For this the sensor array needs to be flexible which has an influence on the silicon components integrated in the tactile sensor.

A key distinguishing feature of this mechanism is that it employs bimorph actuator beams, which have traditionally been used for achieving out-of-plane displacements only. A combination of rigid beams and bimorphs amplifies in-plane displacements and minimizes out-of-plane displacements produced by the bimorphs. A test structure with thermal bimorphs and an embedded resistive heater is fabricated; a maximum displacement of 135 μm is measured at just 3.8 V dc. The mechanism may also be implemented using bimorphs and multimorphs based on piezoelectric effect, electroactive polymers, shape memory alloys, magnetostriction, and electrostriction. Possible applications include movable MEMS stages, integrated Michelson interferometers, temperature sensors, and movable microneedles.","PeriodicalId":202479,"journal":{"name":"2013 Transducers & Eurosensors XXVII: The 17th International Conference on Solid-State Sensors, Actuators and Microsystems (TRANSDUCERS & EUROSENSORS XXVII)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128716455","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
