Tunnel Magnetoresistance Sensors with Magnetostrictive Electrodes: Strain Sensors

Magnetostrictive tunnel magnetoresistance (TMR) sensors pose a bright perspective in micro- and nano-scale strain sensing technology. The behavior of TMR sensors under mechanical stress as well as their sensitivity to the applied stress depends on the magnetization configuration of magnetic tunnel junctions (MTJ)s with respect to the stress axis. Here, we propose a configuration resulting in an...

Functional Electro Stimulation monitoring by bending sensitive magnetostrictive bilayer Sensors

A novel sensor system is presented utilizing bending sensitive bilayers. The sensor system detects the contraction-dynamics of the upper femoral musculature during electric stimulation for diagnostics of muscle fibre recruitment and muscle twitch-dynamics in Functional Electro Stimulation.

Differential read-out circuit for capacitive sensors

Microcontroller-based interface circuit for inductive sensors

This work proposes a fully-digital interface circuit for the measurement of inductive sensors using a low-cost microcontroller (μC) and without any intermediate active circuit. Apart from the μC and the sensor, the circuit just requires an external resistor and a reference inductance so that two RL circuits with a high-pass filter (HPF) topology are formed. The μC appropriately excites such RL ...
