This paper presents an ultra-low power, silicon-integrated readout for resonant MEMS strain sensors. The analogue readout implements a negative-resistance amplifier based on first-generation current conveyors (CCI) that, thanks to the reduced number of active elements, targets both low-power and low-noise. A prototype of the circuit was implemented in a 0.18-µm technology occupying less than 0.4 mm2 and consuming only 9 µA from the 1.8-V power supply. The prototype was earliest tested by connecting it to a resonant MEMS strain resonator.

The Australian Defence Science and Technology Organisation (DSTO) is developing Structural Health Monitoring (SHM) approaches for use on air vehicles. This work describes a potential method for measuring quasi-static strains by monitoring the mechanical-load induced capacitive changes in a piezoelectric sensor. This approach may be combined with the well-documented capability of piezoelectric material to measure dynamic-strain, and may hence allow piezoelectric transducers to be used as low-power, single-solution strain sensors. DSTO has experimentally confirmed that the electrical impedance of a Macro Fiber Composite (MFC) piezoelectric transducer changes with varying strain. In particular, a sensitivity of 1.7 mΩ per με has been observed. With accurate transducer modelling, these changes could be used as an indication of the quasi-static strain in the underlying vehicular structure.

A capacitive MEMS Ultra-Low-Power readout for accelerometers and strain sensors using VerilogA models is presented. The VerilogA model of the accelerometers and strain sensors allows the simulation of a system in a half-bridge configuration. The gain of the system is controlled by integrating pulses from the excitation voltage which accurately controls the Signal-to-Noise ratio. A Figure-of-Merit of [Formula: see text] was achieved for a sensor range of ±2.0 g and ±20,000 με over a 100 Hz bandwidth. Residual motion artefacts are also canceled by the system.

Abstract. Power facilitates goal pursuit, but how does power affect the way people respond to conflict between their multiple goals? Our results showed that higher trait power was associated with reduced experience of conflict in scenarios describing multiple goals (Study 1) and between personal goals (Study 2). Moreover, manipulated low power increased individuals’ experience of goal conflict relative to high power and a control condition (Studies 3 and 4), with the consequence that they planned to invest less into the pursuit of their goals in the future. With its focus on multiple goals and individuals’ experiences during goal pursuit rather than objective performance, the present research uses new angles to examine power effects on goal pursuit.
