We studied the electrical and optical responses of a sensor device based on a nanocomposite comprising CdSe quantum dots (QDs) embedded in an organic matrix to compressive stresses. The sensor converted stresses as low as a few kPa into measurable changes in both current density and electroluminescence (EL) intensity. Two distinct operation regions have been identified: at low stresses below 200 kPa,...
