(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

Stuber, V.L. (author), Deutz, Daniella B. (author), Bennett, James (author), Cannel, David (author), de Leeuw, D.M. (author), van der Zwaag, S. (author), Groen, W.A. (author)Vibrational piezoelectric energy harvesters are being investigated to replace batteries in embedded sensor systems. The energy density that can be harvested depends on the figure of merit, d<sub>33</sub>g<sub>33</sub>, where d<sub>33</sub> and g<sub>33</sub> are the piezoelectric charge and voltage coefficient. Commonly used piezoelectric...journal article 2019
