Flexible electronics and sensors are a key enabling element for the realization of wearables and geometry adaptive devices needed to follow current trends such as the Internet of things or Industry 4.0. Within this paper, we present a new and flexible packaging platform by the fabrication of an ultra-thin and highly flexible printed circuit board (...

‘Safety first’ – all miners know the importance of this slogan. Personal protective equipment, automated or remote-controlled machinery and safety instructions all help to avoid accidents underground. However, there are still many dangerous mining situations where the risk to human life is too high. Modern technologies can help to overcome this obs...

100 years undergound research at the lecturing and experimantal mine Reiche Zeche in Freiberg

The use of modern information and communication technologies (ICT) is an essential driving force for innovations in most social and economic fields. Use of ICT in the mining and special civil engineering sector is also increasing, from ever-improving automation to the vision of fully automated operating mines or tunnel building sites in the context...

Ziel von ARIDuA ist es die Synergien zwischen Robotik und „Internet of Things“ (IoT) Technologien zu erforschen. Das Anwendungsfeld des untertägigen Bergbaus stellt dabei besondere Bedingungen an Technik und Vorgehen. Diesen Herausforderungen stellt sich das interdisziplinäre Forschungsteam und nutzt dabei den Forschungsroboter Julius aus dem Vorgä...

Thin films based on dodecylamine stabilized gold nanoparticles interlinked with different organic molecules are prepared by automatic layer-by-layer self-assembly in a microfluidic quartz crystal microbalance (QCM) cell, to obtain an in situ insight on the film formation by ligand/linker exchange reactions. The influence of interlinking functional...

Modern drill strings for the exploration of oil and gas are equipped with a variety of sensor carrying devices such as Measurement While Drilling (MWD), Logging While Drilling (LWD), and Formation Testing While Drilling (FTWD). These devices generate a large amount of downhole data, such as the orientation of the well, drilling parameters e.g. weig...

The electrokinetic phenomena in charged micro- and nanochannels known as streaming current and streaming potential arise when pressure-driven fluid flow transport by advection induces both a current and a potential at the channel ends. This effect can be used as a sensor/transducer principle and also to generate electricity for sensor power supply...

A printed circuit board (PCB)-based platform for potentiometric chemical sensing in liquid media is proposed. The sensors’ general design and specific issues regarding the reference and indicator electrodes are discussed. Initial experimental data and details of the construction of a solid-state reference electrode (SSRE) are presented. The results...

Field-effect based Electrolyte Insulator Semiconductor (EIS) structures were used to monitor the degradation of cutting fluids under laboratory conditions. An initial set of experiments was carried out to evaluate the sensors’ performance in terms of their sensitivity to degradation-induced pH changes. The results presented here show that the emplo...
