MEMS

[Translate to English:]

We are working on design, manufacture, assembly and testing of micro-/nano-electro-mechanical systems (M/NEMS)

  • for sensing air pollutants (ultrafine dust, nitric oxide, ...),
  • tactile probing of work-piece surfaces (form, roughness, viscoelasticity, ...),
  • energy harvesting (nanowire-based electrical-power generation, on-glass-synthesized solar cells, ...), and storage (anodes of Lithium ion batteries),
  • for basic research on self/impurity diffusion in nanostructures (nanowires, nanofins, ...)
Environmental Sensing
Magnetische Partikel auf piezoresistivem Cantilever

Piezoresistive cantilever sensors are being developed for measuring adsorbed air pollutants such as particles and exhaust gases gravimetrically by resonance frequency shift. To increase sensitivity, the dimensions of the resonator are reduced to the lower µm range and their effective surface area is massively increased using 3D nanostructure networks. Adaptive electronic systems shall ensure optimal signal quality for resonance-frequency tracking.

Tactile & Force Metrology
Doktorand mit Messaufbau bei BZ

Piezoresistive micro-cantilever tactile sensors for testing workpiece surfaces (shape, roughness, viscoelasticity) are being developed for use in industrial applications (in-line, quality control, ..). Actuators required for high-order-mode contact resonance measurements will be represented with integrated heating or piezo actuators.

Energy Harvesting and Storage
Array von Siliziumsäulen mit aufgesetzter Wollastondrahtsonde

We develop methods for structuring semiconductors in nanowire arrays for components for thermoelectric and piezoelectric or photovoltaic energy conversion as well as anodes of Lithium ion batteries. Furthermore, they shall serve as artefacts for testing and validating of metrology for their characterization, including investigations on self diffusion and defect diffusion (at Univ. of Münster, Prof. Bracht).


With crystalline p-conducting silicon, which is synthesized from glass in a low-temperature aluminothermic process, vertical solar cells on glass are being realized. A highly p-conducting layer is inherently present below the silicon layer for the bottom contact. For the top contact an n-doped area is implemented using low-temperature processing.
