Sensor communication applications not only require high performance processing but also flexible and reliable computing. Today, standard microprocessor systems are still application oriented and aren't suitable by implication for reliability-related and safety-related applications. In order to achieve a certain safety integrity level (SIL), several measures, methodologies and especially additional...
Distributed structural health monitoring (SHM) using wireless sensor nodes (WSN) requires frugal spending of the limited energy budget. We propose a reconfigurable heterogeneous architecture, combining a low-power micro-controller (MCU) with a Field-Programmable Gate Array (FPGA), as a means for energy-efficient in-sensor processing. Details covered include a generic communication interface between...
This paper presents a design for an interrogator for a new class of passive wireless sensors. The sensors are intended for deeply embedded structural health monitoring applications. As such, the interrogator must both transmit a signal to elicit a response from the sensor and be able to monitor that response. The interrogator considered transmits in the 2.40-2.48 GHz ISM band and monitors the 2nd...
The paper presents design and implementation of a wireless sensor node suitable for medical applications. As physiological signals are highly redundant, the data compression algorithms (Huffman's coding) are used to save energy and improve the node performance. Design is based on the ARM Cortex M1 processor and implemented in FPGA.
