In this regard, the development of tactile sensors is one of the key technical challenges in advanced robotics and minimal access surgery. In this work we present arrays of 'taxels' (tactile elements) which will be placed on the distal phalange of the humanoid robot in our lab. We present two different designs and implementations. In the first one, microelectrode arrays(MEAs) of 32 elements, with 1 mm center to center distance, have been designed. The taxel is implemented by epoxy-adhering the sensing material (piezoelectric polymer film of PVDF-TrFE) on a microelectrode. Each taxel is intended to be used as an extended gate of an FET (external to the chip); the taxel collects the charge/voltage generated, as consequence of the applied stress, on the deposited piezoelectric polymer film (i.e. the extended gate itself). The second design and implementation integrates both the taxels array and the FET devices, on the same silicon die.","PeriodicalId":118230,"journal":{"name":"2007 Ph.D Research in Microelectronics and Electronics Conference","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129175447","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}

The analog section performs signal acquisition and provides stimuli to the sensor, while the digital section provides digital signal processing IPs (intellectual properties) and a 32-bit RISC (reduced instruction set) DSP (digital signal processor) for important software routines of signal processing, calibration and temperature compensation. An AMR commercial sensor, used for linear position measurement, has been chosen as case study for the verification of the overall interface prototype.

The developed technology aims to fabricate RF-MEMS devices which are able to handle medium RF-power and also targets to be compatible with IC integration.

The prospective of this work is to associate monolithically a power amplifier with this high Q (and then low losses) tuner in order to be able to tune the PAE or even the operating class.","PeriodicalId":118230,"journal":{"name":"2007 Ph.D Research in Microelectronics and Electronics Conference","volume":"196 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124382768","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}
