Particle Sensor Using Solidly Mounted Resonators

Trapped hybrid modes in solidly mounted resonators based on c-axis oriented hexagonal crystals

Graphene as an active virtually massless top electrode for RF solidly mounted bulk acoustic wave (SMR-BAW) resonators.

Mechanical and electrical losses induced by an electrode material greatly influence the performance of bulk acoustic wave (BAW) resonators. Graphene as a conducting and virtually massless 2D material is a suitable candidate as an alternative electrode material for BAW resonators which reduces electrode induced mechanical losses. In this publication we show that graphene acts as an active top el...

Pedestrian Navigation Using Foot-Mounted Inertial Sensor and LIDAR

Foot-mounted inertial sensors can be used for indoor pedestrian navigation. In this paper, to improve the accuracy of pedestrian location, we propose a method using a distance sensor (LIDAR) in addition to an inertial measurement unit (IMU). The distance sensor is a time of flight range finder with 30 m measurement range (at 33.33 Hz). Using a distance sensor, walls on corridors are automatical...

RoμNect: Hand mounted depth sensing using a commodity gaming sensor

In this work, we investigate the applicability of the Kinect depth camera as a robot mounted measurement unit. In contrast to traditional head mounted robot sensors, Kinect is small, cheap and delivers robust depth measurements on a variety of scenes. In the course of applying it on a robot arm, we solve a number of problems: we reduce the sensor working distance to a few centimeters, replace t...

Spatial Distribution of Water Quality Parameters Using Kayak-Mounted Sensor

This testing aimed to determine the feasibility of using a kayak-mounted water quality collection system to measure the spatial distribution of water quality parameters (i.e. temperature, conductivity, pH, turbidity, and dissolved oxygen) in a given body of water. In addition to the water quality data collected by the spatial water quality analyzer, GPS and depth were collected, and the gathere...
