DISTRIBUTED SENSOR SYSTEM
A distributed sensor system is disclosed that provides spatial and temporal data in an operating environment. The distributed sensor nodes can be coupled together to form a distributed sensor system. For example, a distributed sensor system comprises a collection of Sensor Nodes (SN) that are physically coupled and are able to collect data about the environment in a distributed manner. For example, a first sensor node and a second sensor node is formed respectively in a first region and a second region of the semiconductor substrate. A flexible interconnect is formed overlying the semiconductor substrate and couples the first sensor node to the second sensor node. A portion of the semiconductor substrate is removed by etching beneath the flexible interconnect such that the distributed sensor system has multiple degrees of freedom that support following surface contours or sudden changes of direction.
MEMS and NEMS structures
A method of manufacturing an electromechanical systems structure includes manufacturing sub-micron structural features. In some embodiments, the structural features are less than the lithographic limit of a lithography process.

A distributed sensor system is disclosed that provides spatial and temporal data in an operating environment. The distributed sensor nodes can be coupled together to form a distributed sensor system. For example, a distributed sensor system comprises a collection of Sensor Nodes (SN) that are physically coupled and are able to collect data about the environment in a distributed manner.

The MEMS device has: a sensor body having a functional structure configured to transduce a physical or chemical quantity into a corresponding electrical quantity; and a cap bonded to the sensor body and having a first cavity overlying the functional structure. The cap has a supporting portion and a cover portion that form the first cavity. The supporting portion is bonded to the sensor body. The cover portion is bonded to the supporting portion and has an inner wall delimiting on a side the first cavity and facing the functional structure.

Methods and apparatus for preventing solar damage, and other heat-related damage, to uncooled microbolometer pixels. In certain examples, at least some of the pixels of an uncooled microbolometer are configured with a bimetallic thermal shorting structure that protects the pixel(s) from excessive heat damage. In other examples a thermochroic membrane that becomes highly reflective at temperatures above a certain threshold is applied over the microbolometer pixels to prevent the pixels from being damaged by excessive heat.
METHOD FOR ASSEMBLING CONDUCTIVE PARTICLES INTO CONDUCTIVE PATHWAYS AND SENSORS THUS FORMED
A sensor is achieved by applying a layer of a mixture that contains polymer and conductive particles over a substrate or first surface, when the mixture has a first viscosity that allows the conductive particles to rearrange within the material. An electric field is applied over the layer, so that a number of the conductive particles are assembled into one or more chain-like conductive pathways with the field and thereafter the viscosity of the layer is changed to a second, higher viscosity, in order to mechanically stabilise the material. The conductivity of the pathway is highly sensitive to the deformations and it can therefore act as deformation sensor. The pathways can be transparent and is thus suited for conductive and resistive touch screens. Other sensors such as strain gauge and vapour sensor can also be achieved.
