Display Compatible pMUT Device for Mid Air Ultrasound Gesture Recognition

Huang C.H., Demi L., Mao S., Jeong Y., Cheyns D., Rottenberg X., Rochus V., IMEC, BE

1. BACKGROUND Recently, piezoelectric micromachined ultrasound transducers (pMUT) have proved their potential to make a reliable 2D ultrasound array. As shown in Fig. 1, the displacement of piezoelectric material layer is galvanised by electrical signals/acoustic [...]

System Level Analysis for a Locomotive Inspection Robot with Integrated Microsystems

Jeong Y., Kim B., Oh H., Park J-O, Korea Institute of Science & Technology, KR

In this paper, we describe a locomotive inspection robot with integrated microsystems that comprises a micro pump, micro valves, micro channels, a sophisticated pressure amplification system with multi-bellows and biocompatible linear actuators with plastic coated [...]

Optical Characteristics of InAs Quantum Dots influenced by AlGaAs/GaAs Superlattice Barriers

Choi H., Jeong Y., Park Y., Lee J., Leem J-Y, Leem J-Y, Jeon M., Jeong Y., Inje University, KR

We investigated the effect of AlGaAs/GaAs superlattice barriers on the optical properties of InAs quantum dots (QDs) by using photoluminescence (PL) spectroscopy. The samples used in the present work were grown by molecular beam epitaxy [...]
