We provide a broad review of approaches for developing chemosensor systems whose operating parameters can adapt in response to environmental changes or application needs. Adaptation may take place at the instrumentation level (e.g., tunable sensors) and at the data-analysis level (e.g., adaptive classifiers). We discuss several strategies that provide tunability at the device level: modulation ...

Stress induced by ultrasonic dissipation during thermosonic ball bond formation is measured in-situ using microsensors integrated below test bonding pads. The devices are fabricated using a commercial CMOS process, exploiting p + diffusion as piezoresis-tive sensing material. We report time-dependent on-line measurements of the stress-induced resistance change. Higher harmonics of the microsens...

Networks of distributed microsensors are emerging as a compelling solution for a wide range of data gathering applications. Perhaps the most substantial challenge facing designers of small but long-lived microsensor nodes is the need for significant reductions in energy consumption. We propose a power-aware design methodology that emphasizes the graceful scalability of energy consumption with f...

Wireless sensor networks are potentially one of the most important technologies of this century. Advances in hardware development have made available the prospect of low cost, low power, miniature devices for use in remote sensing applications. The combination of these factors has improved the viability of utilizing a sensor network consisting of a large number of intelligent sensors, enabling ...

The vibration analysis is an important step in the design and optimization of microsensors. In most of the cases, COMSOL software is employed to consider the size-dependency on the dynamic behavior in the MEMS sensors. In this paper, the Modified Couple Stress Theory (MCST) is used to capture the size effect on dynamic behavior in a microsensor with two layers of the silicon and piezoelectric. ...

The tire pressure monitoring system (TPMS) can not only make the driver more safety, but also save fuel and protect the tire. Tire safety is attracting the driver's attention, the United States had developed laws to enforce the TPMS installation in the car. In this paper, the basic structure and the implement method of TPMS are introduced. The SAW theory and some surface acoustic wave (SAW) tem...
