Energy harvesting from ambient vibrations has become an interesting topic for powering wireless sensor networks. Resonant microdevices based on MEMS have become of central importance at low frequency. The power produced at resonance is at least one order of magnitude larger than off ... Per saperne di più
Electrostrictive polymers have been of significant interest over the last years for energy harvesting. Principle is based on the conversion of a mechanical deformation into electricity. The stored energy basically depends on the mechanical strain induced into an electrostrictive polymer ... Per saperne di più
A sharp tip approached perpendicular to a conducting surface at subnanometer distances and biased with a small voltage builds a junction across which electrons can be transferred from the tip apex to the nearest surface atom by direct quantum mechanical tunneling. Such a junction is used ... Per saperne di più
The use of optical sensors in the industry is still growing. A transmission of signal from the sensors is mostly done by optical fibers. Switching the signals from optical paths may be done by using micromechanical silicon switches. The main advantage is an ability to transmit data from ... Per saperne di più
Designing and constructing a lab-on-a-chip device poses a variety of questions. Transport of all required substances, detection of the analyte and its deposition on a sensor have to be incorporated. Different strategies have been developed to achieve good coverages of the sensor, like ... Per saperne di più
Magnetophoresis is a process of great interest for novel applications based on magnetic nanoparticles and colloids. Environmental applications like wastewater treatments and pollutant removal, biomedical applications like protein isolation, drug delivery, magnetic hyperthermia for cancer ... Per saperne di più
The simulation of the piezoelectric actuation of the micro-cantilever is presented. Lead Zirconate Titanate (PZT) was chosen for the device fabrication design, due to its thin film processing flexibility. Four layers compose the cantilever structures presented in this work: PZT ...
