<p>A pressure transducer (10) that converts a pressure distribution directly into a visible image. The transducer (10) may be viewed as comprising a two-layered structure sandwiched between first and second electrodes that provide a bias potential. The intermediate layers comprise a piezoresistive layer (12) and a light emitting layer (14). The piezoresistive layer (12) includes a material or structure whose resistivity varies as a function of pressure. The light emitting layer (14) is constructed from a material or structure whose light output varies in relation to the current passing through the layer.</p> |
