Deutz, D.B. (author), Mascarenhas, N.T. (author), van der Zwaag, S. (author), Groen, W.A. (author)Composites of aligned (K,Na,Li)NbO<sub>3</sub> (KNLN) piezoceramic particles in a PDMS polymer matrix are presented as promising materials for flexible sensors and energy harvesters. Their ease of processing is matched with a relatively high damage tolerance and piezoelectric performance at low dielectric loss. To maximize piezoelectric...journal article 2017

Deutz, D.B. (author), Mascarenhas, N.T. (author), Schelen, J.B.J. (author), de Leeuw, D.M. (author), van der Zwaag, S. (author), Groen, W.A. (author)A highly sensitive, lead-free, and flexible piezoelectric touch sensor is reported based on composite films of alkaline niobate K<sub>0.485</sub>Na<sub>0.485</sub>Li<sub>0.03</sub>NbO<sub>3</sub> (KNLN) powders aligned in a polydimethylsiloxane (PDMS) matrix. KNLN powder is fabricated by solid-state sintering and consists of microcubes. The...journal article 2017

Deutz, D.B. (author), Mascarenhas, N.T. (author), van der Zwaag, S. (author), Groen, W.A. (author)In this study, the influence of Li substitution on the piezoelectric performance of lead-free K<sub>0.5</sub>Na<sub>0.5</sub>NbO<sub>3</sub> (KNN)-epoxy composites is explored. KNN piezoceramic particles modified with 0-12 mol% of Li are prepared via a double calcination technique, resulting in a perovskite particulate which transitions from...journal article 2016
