Passive UHF RFID Systems for Capacitive Sensing Applications

Kerem Kapucu

In this work, a complete passive UHF RFID system for capacitive sensing applications is developed to be used in food quality monitoring and supply chain management. All the components of the RFID system including the base station, the base station antenna, ...

Electrostatic Spray Ionization Method

Liang Qiao, Yu Lu, Elena Tobolkina, Romain Sartor

In an electrostatic spray ionization method for spraying a liquid layer from an insulating plate 2, the plate is arranged between two electrodes 1, 4. A constant high voltage power supply 3 is provided and an electric circuit is used to charge and discharg ...

Remotely-Powered Batteryless Implantable Local Temperature Monitoring System for Freely Moving Mice

Brown adipose fat tissue of a mouse dissipates the animal’s energy in the form of heat. Chronically recording the temperature of this tissue helps biologists to study the metabolism of the animal and gain new insights about the obesity in humans. Such temp ...

A 15 mu W 5.5 kS/s Resistive Sensor Readout Circuit with 7.6 ENOB

Catherine Dehollain

A low power SAR logic-based resistive sensor readout circuit is proposed. A high sensitivity thermistor is used for local temperature measurements. The need for a low-noise front-end voltage amplifier is avoided by employing time-domain operation. In each ...

Power supply energy optimization for ultra low-power wireless sensor nodes

Pierre-André Farine, Alexis Boegli, Mitko Tanevski

The wireless sensor nodes are most energy-efficient when they operate at the minimal operating voltage. The nominal voltage of the batteries used is often significantly higher. This paper analyzes DC-DC power conversion from the point of view of ultra low- ...

A Demand-Response Calculus with Perfect Batteries

Jean-Yves Le Boudec, Dan-Cristian Tomozei

We consider an electricity consumer equipped with a perfect battery, who needs to satisfy a non-elastic load, subject to external control signals. The control imposes a time-varying upper-bound on the instantaneous energy consumption (this is called ``Dema ...

Modular DC/DC Converter for DC Distribution and Collection Networks

Stephan Kenzelmann

A major change in the electrical transmission and distribution system is taking place in Europe at the moment. The shift from a centralised energy production to a distributed generation profoundly changes the behaviour of the grid. Environmental or social ...

Beyond Scaling

Luca De Michielis

Over the recent decades, the balance between increasing the complexity of computer chips and simultaneously reducing cost per bit has been accommodated by down-scaling. While extremely successful in the past, this approach now faces grave limitations leadi ...
