WiMDaD Wire Mesh Damage Detection
Composite materials are nowadays used in many technical fields. Blades of wind power plants or aircraft parts, for example, are made out of these materials.
Measurable latent heat storage systems
Latent heat stores (PCM stores) are heat stores that store a large proportion of the thermal energy supplied to them in the form of conversion enthalpy, the energy required for the transition from one phase (solid/liquid/gaseous) to another. An invention by Westfälische Hochschule and Bochum University of Applied Sciences can determine the stored heat content using piezoelectric elements.
Skyrmion defect
In theoretical physics, a model of topologically stable soliton vortices in fields is referred to as a skyrmion. These vortices behave like particles or quasiparticles of finite mass. The invention of the University of Duisburg-Essen describes a static and dynamic method for recording the distribution and movement of a parameter over a sample with quasiparticles, e.g. skyrmions.
Rain gutter water level monitoring
Gutter blockages caused by leaves, dirt and other debris can prevent the flow of water in the gutter, which can lead to considerable damage and problems. Water can spill over the sides of the gutter, causing water damage to the foundations or other parts of the building. In addition, standing water in the gutter can attract insects such as mosquitoes and serve as a breeding ground. In colder climates, the accumulated water can freeze and form ice dams that damage the roof or the gutter itself. Researchers at the University of Siegen have found an innovative solution to this problem by equipping the gutters with a water level sensor.
Quick, low-cost refractometer
In order to adapt optical systems and lenses precisely to an application, it is necessary to know the material properties and the optical parameters of the lens material. A new method developed by Düsseldorf University of Applied Sciences determines the dispersion (wavelength dependence of the refractive index) using a simplified setup without moving parts and even without a wavelength scan.
Scalable photodetector
Most optical sensors require an external supply voltage - not so the novel scalable photodetector from the University of Duisburg-Essen. This photodetector can also be processed or manufactured on a foil basis using the MOCVD process. Possible applications include implants without a battery for medical technology.
Wiegand position encoder with Gray code generation

An improvement in high-resolution gigahertz and terahertz spectroscopy, now enables sensitive measurements of high-frequency signals over a wide spectral range. The application areas for this technology are in chemical analysis as well as quality control: The sensitivity in the measurement of analysis samples with high-frequency signals can thus be significantly increased.
Selective ion storage
The measurement of molecular spectra is important for the chemical or pharmaceutical industry. The new method from the University of Cologne is suitable for the acquisition of any kind of spectra of ion species such as rotational, vibrational, Ro-vibrational, electronic spectra. The composition of the spin states of electrons and nuclei can also be determined. This opens up completely new areas of application.

Quantum Dot Arrays
Nanostructures are suitable for the fabrication of optoelectronic devices, but their fabrication is costly. Their utility, however, is immense: mode profiles can be created in a direct way, for example, to "attract" lasers or to adjust densities for single quantum dot applications such as single photon sources.
Photoacoustic gas sensor
Gas sensors are used for the detection of gaseous substances. Resistive measurement methods are often used, but their signal values often exhibit drift due to aging or lose selectivity. A new type of photoacoustic gas sensor (PAS) from the Technical University of Dortmund is different: it detects target gases very precisely and selectively.
Laser absorption spectroscopy
The new method from TU Dotmund uses laser absorption spectroscopy to monitor air quality in order to measure trace gases present, such as methane or CO2. The improved intra-cavity absorption spectroscopy allows the application in measurement technology, industrial process monitoring as well as safety engineering.
Optical Strain Gauge
The novel and all-optical strain measurement method is highly accurate and cost-effective. The strain is determined by means of an optical fiber-based purely optical method and thus also enables use in harsh application fields, such as explosion-proof areas or where disturbing pulsating magnetic fields interfere with conventional strain measurement sensors.
