Word count Dofollow links on the home page External: 34 Internal: Measurement of wireless pressure sensors fabricated in high temperature co-fired ceramic MEMS technology. Inexpensive with large volume production. The current flowing through the wire rapidly increases the sensitivity, Figure The wire gets held in place and stretched by placing sticky tape over the wire ends. HTCC also has some restrictions in the use of conductor material; a refractory metal must to be used [12]. One mode consists of keeping a wire at a constant resistance, i.

    Microscale Ceramic Pressure Sensor Element for a Carbon Isotope Exploration

    Figure 9. Life has a bigger uptake of 12C than non-life, and if there is, or has been, life on other planets, the same ratio of carbon isotopes for Earth-like life is expected [1].

    With the second technique, the wire has been threaded through a drilled hole which has its center aligned to the center of the cavity, Figure 20 right. This assumes a perfect heat gradient and a hermetically sealed cavity with no impact from the outer atmosphere; this comparison is focused on how the heat dissipates. The largest heat emission from the wire was observed at its main bend, Figure 31 left. To enable connections, the heat sink had to be elevated, why it was put on a bigger heat sink of brass, Figure

    Two wire alignment schemes showing the center aligned wire holes top and the side aligned holes bottom. Reasons for the improved development are the increased experience of manufacturing after every batch, developing the wire threading technique more, which in the end yielded more working devices. Electrical circuit used for measuring the resistance change of the pressure sensor.

    The geometric simplicity makes the integration to the lab on a chip very feasible.
