  1. 1. Towards an on-chip power supply: Integration of micro energy harvesting and storage techniques for wireless sensor networks

    Author : Agin Vyas; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Microsuperca- pacitor; On-chip power supply.; Piezoelectric energy harvester; CMOS compatible; MEMS;

    Abstract : The lifetime of a power supply in a sensor node of a wireless sensor network is the decisive factor in the longevity of the system. Traditional Li-ion batteries cannot fulfill the demands of sensor networks that require a long operational duration. READ MORE

  2. 2. Real-time signal processing in MEMS sensor-based motion analysis systems

    University dissertation from Västerås : Mälardalen University

    Author : Jiaying Du; Maria Lindén; Helena Grip; [2019]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; elektronik; Electronics;

    Abstract : This PhD thesis focuses on real-time signal processing for hardware-limited micro-electro-mechanical system (MEMS) sensor-based human motion analysis systems. The aim of the thesis is to improve the signal quality of MEMS gyroscopes and accelerometers by minimizing the effects of signal errors, considering the hardware limitations and the users' perception.

  3. 3. Signal processing for MEMS sensor based motion analysis system

    University dissertation from Västerås : Mälardalen University

    Author : Jiaying Du; Maria Lindén; Nicholas Wickström; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Computer Science; datavetenskap;

    Abstract : Sensor systems for motion analysis represent an important class of embeddedsensor systems for health, and are usually based on MEMS technology(Micro-electro-mechanical systems). Gyroscopes and accelerometers are two examples of MEMS motion sensors that are characterized by their small size,low weight, low power consumption, and low cost. READ MORE

  4. 4. Three-component digital-based seismic landstreamer Methodologies for infrastructure planning applications

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Bojan Brodic; Alireza Malehmir; Christopher Juhlin; André Pugin; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; landstreamer; multicomponent seismic; shear-waves; surface-waves; Geofysik med inriktning mot fasta jordens fysik; Geophysics with specialization in Solid Earth Physics;

    Abstract : To support urban infrastructure planning projects, along with various other near-surface applications, a multicomponent landstreamer was developed. The landstreamer was built with broadband (0-800 Hz), three-component (3C) micro-electro-mechanical system (MEMS) sensors. READ MORE

  5. 5. On GPS receiver architectures

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Jonas Thor; [2003]
    Keywords : ;

    Abstract : Navigation can be described as the art of finding the way from one location to another. Clearly navigation is something that we perform in our every day lives and the role of navigation can not be underestimated. There exist many technologies that implement various navigation systems to aid in this process. READ MORE
