Abstract:
1. An analysis device for use with an external testing apparatus to detect the presence of an analyte in a test sample, the device comprising: a transducer formed of a layer of pyroelectric or piezoelectric material sandwiched between first and second electrode layers, the transducer being arranged to produce an electrical voltage across the electrode layers in response to heating or straining of the pyroelectric or piezoelectric material layer; and first and second stiffening elements for the transducer, the transducer being sandwiched between the stiffening elements, each of the stiffening elements defining a planar surface for maintaining the transducer in a flat condition, wherein each of the stiffening elements exposes a portion of a respective electrode layer of the transducer for electrically connecting the transducer to the external testing apparatus, the exposed portions being laterally offset from each other such that the exposed portions are each supported across the whole of their area by the stiffening element on the opposite side of the transducer.
