摘要： A temperature sensing device includes two or more strips, wherein each of the two or more strips comprises a shape memory polymer adapted to undergo a change in a modulus of elasticity at a thermal transition temperature. A method comprises contacting two or more strips with an item, wherein each strip comprises a shape memory polymer adapted to undergo a change in a modulus of elasticity at a thermal transition temperature; equilibrating the two or more strips with the item; and determining a temperature range of the item by observing whether any of the two or more strips underwent a decrease in stiffness and/or increase in flexibility caused by the change in the modulus of elasticity of the shape memory polymer.

摘要： An exhaust system includes an exhaust conduit; a piezoelectric patch secured to the exhaust conduit; a sensor in operative communication with the exhaust conduit; and a controller in operative communication with the piezoelectric patch and the sensor, wherein the controller is configured to provide a signal to the piezoelectric patch and modify a sound emitted from the exhaust system. A method includes producing an exhaust gas in an exhaust conduit of an exhaust system; measuring an acoustic property of the exhaust gas, an acoustic property of the exhaust conduit, or a combination comprising at least one of the foregoing acoustic properties; applying an electrical signal to a piezoelectric patch, wherein the piezoelectric patch is secured to the exhaust conduit; and deforming the piezoelectric patch mechanically to modulate a sound emitted from the exhaust system.
