Abstract: A perfusive tissue phantom is disclosed. An example tissue phantom includes a chamber with fluid inlets disposed on a first side and fluid outlets disposed on a second side spaced apart from the first side. The tissue phantom also includes a hydrogel region connected to at least one of the fluid inlets and including a permeable hydrogel with structural characteristics that simulate a type of tissue. The tissue phantom also includes a microfluidic conduit coupled to at least one of the fluid inlets. The microfluidic conduit is a flexible, semi-permeable fiber that simulates a blood vessel. The structural characteristics of the permeable hydrogel may include a selected density, porosity, rigidity and dimension that approximate a target density, porosity, rigidity and dimension of interstitial space of the type of tissue.

Abstract: The application relates to an apparatus which comprises at least one portion of artificial skin (103) and a plurality of sensors (105) dispersed within the at least one portion of artificial skin (103). The plurality of sensors (105) have at least one physical property which is configured to be modified when the plurality of sensors (105) are exposed to a parameter such that the modification of the physical property can be detected by an external detector (211). The application also relates to detection systems comprising such apparatus.

Abstract: An apparatus for sensing, the apparatus comprising: a plurality of genetically modified sensors and a transducer array. The plurality of genetically modified sensors comprise a plurality of subsets of sensors wherein the sensors are genetically modified so as to provide an output in response to one or more chemicals. The plurality of genetically modified sensors are genetically modified in a non-correlated manner so that different subsets of sensors are configured to provide a different affinity to different chemicals. The transducer array, comprises a plurality of pixels, wherein different subsets of the plurality of genetically modified sensors are coupled to different pixels so as to cause the pixels to provide outputs dependent upon the genetic modification of the subset of sensors coupled to the pixel. Detection of one or more chemicals by one or more of the genetically modified sensors causes an identifiable output signal to be provided by the transducer array.
