A high-sensitivity sensor and sensor array is proposed which can be used for infrared (IR) detection and imaging, and for chemical, biological agent and other types of sensing. The sensing elements consist of microresonators. Calculation shows that an array of microresonators in the 200 MHz to 1 GHz range can be the basis of an uncooled IR imaging ...

Sensor Arrays: Arrays of Micro- and Nanoelectrodes
2014This chapter deals with the principles of functioning and electroanalytical usefulness of arrays of micrometer and nanometer-sized electrodes. We discuss arrays of microelectrodes both individually shaped and interdigitated. In the field of nanostructured electrodes, both nanoelectrode ensembles (random arrays) and ordered arrays are presented.

SPIE Proceedings, 2009
Microcavity optical resonators have been investigated in the last years extensively for possible applications in optical communication (switching, filtering, and multiplexing), to investigate cavity quantum dynamic effects, and for sensor applications. The most recent area of application is bio-sensing.

Current Opinion in Chemical Biology, 2002
Imaging optical fibres have been etched to prepare microwell arrays. These microwells have been loaded with sensing materials such as bead-based sensors and living cells to create high-density sensor arrays. The extremely small sizes and volumes of the wells enable high sensitivity and high information content sensing capabilities.

Acoustic vector sensor array processing
[1992] Conference Record of the Twenty-Sixth Asilomar Conference on Signals, Systems & Computers, 1994An approach is proposed for localization of acoustic sources using an array of sensors for which the measurement of each sensor is a vector consisting of the acoustic pressure and acoustic particle velocity. A compact expression is derived for the Cramer-Rao bound (CRB) on the estimation errors of the source direction-of-arrival (DOA) parameters in the

Miniaturized Chemical Multiplexed Sensor Array
Journal of the American Chemical Society, 2003Miniaturized tin oxide semiconductor sensors are fabricated directly by site-specific dip-pen nanopatterning using precursor inks derived from the sol-gel method. The good flow characteristics and strong affinity of the sols to measurement electrodes enable intimate contact.

A Microfluidic Ion Sensor Array
Small, 2020AbstractA balanced concentration of ions is essential for biological processes to occur. For example, [H+] gradients power adenosine triphosphate synthesis, dynamic changes in [K+] and [Na+] create action potentials in neuronal communication, and [Cl−] contributes to maintaining appropriate cell membrane voltage.

Molecularly imprinted polymer sensor arrays
Current Opinion in Chemical Biology, 2010The sensor array format has proved an effective method of transforming sensors of modest selectivity into highly selective and discriminating sensors. The primary challenge in developing new sensor arrays is collecting together a sufficient number of recognition elements that possess different binding affinities for the analytes of interest.

Silica microspheres array strain sensor
Optics Letters, 2014An optical fiber sensor based on arrays of silica microspheres is proposed. The microspheres are produced separately using a fusion splicer and then also connected in series by fusion splicing. Three different sensors are presented, differing by the number of microspheres.

A transparent oxygen sensor array
Annals of Biomedical Engineering, 1986The development of a transparent array of independently connected oxygen sensors is described. With an appropriate sensor pattern, this device may be useful to monitor the distribution of oxygen on the surface of tissues, while permitting simultaneous tissue visualization.
