We present a unique lateral bulk resonance mode with a lateral strain profile that resembles a shirt button that we transduce piezoelectrically in a MEMS disk resonator. This button-like (BL) mode offers the 3-fold benefits of (1) intrinsic feedthrough cancellation using fully-differential transduction, (2) strong piezoelectric coupling from the associated strain profile, and (3) higher quality (Q)...
We demonstrate a MEMS translational stage that uses electrowetting-on-dielectric (EWOD) as the actuating mechanism. Our EWOD stage is capable of linear translation with resolution of 10 μm over a maximum range of 130 μm and angular deflection of approximately ±1° while eliminating solid-solid contact. The range and resolution can be readily improved via higher base contact angle and lower contact...
In this work, we present a fully-differential wine-glass (WG) mode MEMS resonator fabricated in thin film Aluminum Nitride (AlN) on Silicon (Si) MEMS technology for resonant sensing applications in liquids. Our finite element (FE) simulations show that the strain fields associated with this mode are well suited for fully-differential piezoelectric transduction. We experimentally demonstrate that the...
A promising acetylcholine biosensor based on graphene-PEDOT:PSS (GR-PEDOT:PSS) and bienzyme, choline oxidase (ChOx) and acetylcholine esterase (AChE), modified electrode was successfully fabricated. GR-PEDOT:PSS ink was directly dropped on the screen printed carbon electrode (SPE), and then ChOx and AChE in the optimized loading ratio were immobilized on GR-PEDOT:PSS/SPE by the 10% glutar-aldehyde...
We propose a low-power-consumption CO2 gas sensor using ionic liquids We use ionic liquids of imidazolium salts EMIMBF4 EMIMTFSI and BMIMHFA The impedance of the ionic liquids decreases along with increase of the CO2 gas concentration By measuring the impedance of the ionic liquids we could estimate the CO2 gas concentration of the atmosphere This experiment showed that measurement resolution of our...
