UV-Assisted Gate Bias Cycling in Gas-Sensitive Field-Effect Transistors
Proceedings, 2018 Static and dynamic responses of a silicon carbide field-effect transistor gas sensor have been investigated at two different gate biases in several test gases. Especially the dynamic effects are gas dependent and can be used for gas identification.

Tuneable Q-Factor of MEMS Cantilevers with Integrated Piezoelectric Thin Films
Sensors, 2018 In atomic force microscopes (AFM) a resonantly excited, micro-machined cantilever with a tip is used for sensing surface-related properties. When targeting the integration of AFMs into vacuum environments (e.g., for enhancing the performance of scanning ...

An extended actuator cylinder model: Actuator‐in‐actuator cylinder (AC‐squared) model [PDF]
Wind Energy, 2019 AbstractIn this paper, the actuator‐in‐actuator cylinder (AC‐squared) model is presented. This model is an extension of the original actuator cylinder model of Madsen and is capable of modelling the effect of a two concentric actuation surfaces in 2D. The induced velocity at every point in the 2D field is affected by the force field acting on the two ...

Dynamic Channel Calibration on a Crystal-Free Mote-on-a-Chip
IEEE Access, 2019 The single chip integration of a wireless sensor node would allow for cheap, low-power, dust-size devices. The key to realizing this vision is to eliminate bulky off-chip frequency references such as crystal oscillators or resonators, and their ...

Polymers, 2021 Following the natural muscle antagonist actuation principle, different adaptations for “artificial muscles” are introduced in this work. Polypyrrole (PPy) films of different polymerization techniques (potentiostatic and galvanostatic) were analyzed and their established responses were combined in several ways, resulting in beneficial actuation modes. A

, 2017 IntroductionThe term actuation problem was first introduced and defined by Weinreich, Labov and Herzog (1968:102). In their words: (1) The actuation problemWhat factors can account for the actuation of changes? Why do changes in a structural feature take place in a particular language at a particular time, but not in other languages with the same ...

Tailored measurement setup for the contactless characterization of MEMS resonators at the wafer level [PDF]
Journal of Sensors and Sensor SystemsStatistical analysis of microelectromechanical system (MEMS) resonator devices in an early stage of device fabrication is challenging since actuation and sensing of the frequency-dependent response characteristics are often impossible before electrical ...
