This　paper　presents　a　micromachined　piezoelectric　resonator　based　on　microcantilever　with　out-of-plane　vibration　for　liquid　density　and　viscosity　determination.　The　microcantilever　mainly　contained　a　T-beam　and　four　piezoresistive　beams,　which　has　significantly　different　vibration　modes　in　liquid　compared　with　fundamental　plate　microcantilever.　The　focus　was　set　on　2nd　out-of-plane　vibrational　mode,　excited　in　a　novel　wave-shaped　operation　mode　in　liquid　media.　Finite　element　simulations　were　performed　to　optimize　the　operation　mode　and　analyze　the　resonance　characteristics.　A　high　quality　factor　of　223　was　achieved　in　cyclohexane　at　71　kHz,　and　the　sensitivity　was　calculated　by　four　organic　liquids,　and　34　Hz/$\left(\mathbf{k　g}　\cdot　\mathbf{m}^{-3}\right)$　was　achieved.　The　results　indicated　that　the　proposed　novel　resonator　with　wave-shaped　mode　reached　high　quality　factor　as　well　as　high　sensitivity　in　liquids　measurements.　©　2020　IEEE.
