Journal ArticleDOI
Artificial sensory hairs based on the flow sensitive receptor hairs of crickets
Marcel Dijkstra,J.J.J. van Baar,Remco J. Wiegerink,Theodorus S.J. Lammerink,J. de Boer,Gijsbertus J.M. Krijnen +5 more
TL;DR: In this article, the wind-receptor hairs of crickets are used to detect the movement of the membranes of suspended SixNy membranes, and capacitance versus voltage, frequency dependence and directional sensitivity measurements have been successfully carried out on fabricated sensor arrays.
Journal ArticleDOI
Micromachined structures for thermal measurements of fluid and flow parameters
J.J.J. van Baar,Remco J. Wiegerink,Theodorus S.J. Lammerink,Gijsbertus J.M. Krijnen,Michael Curt Elwenspoek +4 more
TL;DR: In this paper, thermal sensor-actuator structures are proposed that can be used to measure various fluid parameters such as thermal conductivity, flow velocity, heat capacity, kinematic viscosity and pressure.
Proceedings ArticleDOI
Arrays of cricket-inspired sensory hairs with capacitive motion detection
J.J.J. van Baar,Mindert Dijkstra,Remco J. Wiegerink,Theodorus S.J. Lammerink,R. de Boer,Gijsbertus J.M. Krijnen +5 more
TL;DR: In this paper, the SU-8 hairs were suspended on membranes containing electrodes to form the variable capacitors, which were then used to measure capacitance versus voltage, frequency dependency and directional sensitivity.
Proceedings ArticleDOI
Fabrication of arrays of artificial hairs for complex flow pattern recognition
J.J.J. van Baar,Mindert Dijkstra,Remco J. Wiegerink,Theodorus S.J. Lammerink,Gijsbertus J.M. Krijnen +4 more
TL;DR: In this article, a combined bulk/surface micromachining process was developed to integrate high-density arrays of artificial hairs for flow pattern measurements based on drag force, and first fabrication results show the possibility to fabricate out-of-plane hairs without reverting to micro-assembly technologies.
Journal ArticleDOI
Application of a microflown as a low-cost level sensor
J.W. van Honschoten,J.J.J. van Baar,H.E. de Bree,Theodorus S.J. Lammerink,Gijsbertus J.M. Krijnen,Michael Curt Elwenspoek +5 more
TL;DR: In this article, a spirit level temperature sensor based on the temperature difference of two identical heaters, caused by buoyancy of air, is presented. But the first experiments, using dc signals only, show adequate sensitivity, although high-accuracy operation is hampered by thermal drift.
