“…As it has been presented in [2] and [3], Tyndall has developed modular wireless platforms in different formats for deployment in WSN. The multi-sensors dies can then be attached to these platforms as it has already been demonstrated for temperature and humidity on a 25mmx25mm board [1].…”

“…The interface boards exist in both 25mm×25mm and 10mmx10mm form factors and allow a combination of different sensors to be connected to computational and RF components [1], [2]. Since discrete sensors are bulky, expensive and consume board area, the use of MEMS-based integrated sensors will allow further miniaturisation of the platform.…”

“…Such networks, generally referred to as wireless sensor networks (WSNs) are finding applications in areas that require deployments of a large number of sensor and actuator nodes to monitor environmental stresses in real time in order to detect potential failures and localized anomalies, in areas such as agriculture, telecommunications, building energy management and supply chain management [1][2][3][4]. In order to unobtrusively embed wireless sensors within everyday objects, it is important that WSN hardware becomes cheaper, further miniaturized and features reduced power consumption.…”

“…Wireless sensors, often referred to as "nodes" or "motes" [1] are attractive for this purpose because of their small size, low power consumption, and potentially low cost of fabrication. They are also easy to interrogate, and communication between units is used to build up a network that gathers all the information needed in real time and either transmits or stores it for later use if connected to a memory [2][3][4]. Depending on the target application, sensors can be interfaced with a range of wired or wireless communications interfaces as required.…”

Development of a Microelectromechanical System (MEMS)-Based Multisensor Platform for Environmental Monitoring

Recent progress in data processing, communications and electronics miniaturization is now enabling the development of low-cost wireless sensor networks (WSN), which consist of spatially distributed autonomous sensor modules that collaborate to monitor real-time environmental conditions unobtrusively and with appropriate levels of spatial and temporal granularity. Recent and future applications of this technology range from preventative maintenance and quality control to environmental modelling and failure analysis. In order to fabricate these low-cost, low-power reliable monitoring platforms, it is necessary to improve the level of sensor integration available today. This paper outlines the microfabrication and characterization results of a multifunctional multisensor unit. An existing fabrication process for Complementary Metal Oxide Semiconductor CMOS-compatible microelectromechanical systems (MEMS) structures has been modified and extended to manufacture temperature, relative humidity, corrosion, gas thermal conductivity, and gas flow velocity sensors on a single silicon substrate. A dedicated signal conditioning circuit layer has been built around this MEMS multisensor die for integration on an existing low-power WSN module. The final unit enables accurate readings and cross-sensitivity compensation thanks to a combination of simultaneous readings from multiple sensors. Real-time communication to the outside world is ensured via OPEN ACCESSMicromachines 2011, 2 411 radio-frequency protocols, and data collection in a serial memory is also made possible for diagnostics applications.
