  • Combination of Laser and Thermal Sintering of Thermoelectric Ca3Co4O9 Films 
    Wolf, Mario; Rehder, Lena; Steinbach, Frank; Abt, Marvin; Hinterding, Richard; Overmeyer, Ludger; Feldhoff, Armin (Weinheim : Wiley-VCH Verl., 2021)
    The manufacturing technology of thermoelectric materials is laborious and expensive often including complex and time-intensive preparation steps. In this work, a laser sintering process of the oxide-based thermoelectric ...
  • An electro-mechanical dynamic model for flexoelectric energy harvesters 
    Thai, Tran Quoc; Zhuang, Xiaoying; Rabczuk, Timon (Dordrecht [u.a.] : Springer Science + Business Media B.V, 2022)
    Flexoelectricity is a universal electro-mechanical coupling effect that occurs in dielectrics of all symmetric groups and becomes dominant at the micro- and nano-scales. It plays an important role in evaluating ...
  • Electronic transport in CdSe nanoplatelet based polymer fibres 
    Miethe, Jan F.; Schlosser, Anja; Eckert, J.Gerrit; Lübkemann, Franziska; Bigall, Nadja C. (Cambridge : Royal Society of Chemistry, 2018)
    One of the most significant objectives in the field of nanotechnology is the transfer of specific properties of smaller nanoparticle building blocks into larger units. In this way, nanoscopic properties can be linked to ...
  • High power factor vs. high zT-A review of thermoelectric materials for high-temperature application 
    Wolf, Mario; Hinterding, Richard; Feldhoff, Armin (Basel : MDPI AG, 2019)
    Energy harvesting with thermoelectric materials has been investigated with increasing attention over recent decades. However, the vast number of various material classes makes it difficult to maintain an overview of the ...
  • Inverse design of topological metaplates for flexural waves with machine learning 
    He, Liangshu; Wen, Zhihui; Jin, Yabin; Torrent, Daniel; Zhuang, Xiaoying; Rabczuk, Timon (Amsterdam [u.a.] : Elsevier Science, 2020)
    The mechanical analog to the topological insulators brings anomalous elastic wave properties which diversifies classic wave functions for potential broad applications. To obtain topological mechanical wave states with good ...
  • Optical autonomous sensor module communicating with a smartphone using its camera 
    Dudko, Uliana; Pflieger, Keno; Overmeyer, Ludger (Bellingham, Wash. : SPIE, 2019)
    Wireless optical communication is a viable alternative to conventional RF technology. Our novel design combines optical communication and energy harvesting in one device with a size of 30 x 10 x 5 mm using the latest ...
  • Optimal design of piezoelectric actuators for shunt damping techniques 
    Neubauer, Marcus (Warsaw : Polish Academy of Sciences, Institute of Fundamental Technological Research, 2014)
    In vibration control with piezoceramics, a high coupling of the piezoelement with the structure is desired. A high coupling improves the damping performance of passive techniques like shunt damping. The coupling can be ...
  • Sparse representations and harmonic wavelets for stochastic modeling and analysis of diverse structural systems and related excitations 
    Pasparakis, George D. (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2022)
    In this thesis, novel analytical and computational approaches are proposed for addressing several topics in the field of random vibration. The first topic pertains to the stochastic response determination of systems with ...
