Low-Power Direct Resistive Sensor-to-Microcontroller Interfaces

Measuring Dynamic Signals with Direct Sensor-to-Microcontroller Interfaces Applied to a Magnetoresistive Sensor

This paper evaluates the performance of direct interface circuits (DIC), where the sensor is directly connected to a microcontroller, when a resistive sensor subjected to dynamic changes is measured. The theoretical analysis provides guidelines for the selection of the components taking into account both the desired resolution and the bandwidth of the input signal. Such an analysis reveals that...

Integrated Low Power Ultrasound Sensor Interfaces

Imagine that the technical development can change the ultrasound measurement systems used for fetus feature detection from the large piece of machinery today, to a wireless coin size system tomorrow. The factor that has reduced the size of electronic systems over time is integration and integrated circuits. In this thesis circuit simulator models of complete ultrasound systems are used to desig...

Low Power Resistive Oxygen Sensor Based on Sonochemical SrTi0.6Fe0.4O2.8 (STFO40)

The current paper reports on a sonochemical synthesis method for manufacturing nanostructured (typical grain size of 50 nm) SrTi0.6Fe0.4O2.8 (Sono-STFO40) powder. This powder is characterized using X ray-diffraction (XRD), Mössbauer spectroscopy and Scanning Electron Microscopy (SEM), and results are compared with commercially available SrTi0.4Fe0.6O2.8 (STFO60) powder. In order to manufacture ...

Improving the Resolution in Direct Inductive Sensor-to-Microcontroller Interface

The paper describes an improved direct inductive sensor to microcontroller interface by incorporating external MOSFET transistors. In such a way, the measured discharging time interval can be increased (through the discharging time constant) which results in increased resolution for a given time base. The experimental results show that the resolution of the measurements can be significantly imp...
