Problems solved by technology

However, if, for example, the optimum peak strain for an element is 3000 microstrain, subjecting an electromechanical transducer element to that amount of strain may result in damage to the element
Also, deformations within a tire during operation are often inconsistent in magnitude and direction, making it difficult to properly orient the transducer elements to efficiently utilize the energy from the deformations

Abstract

A bridge patch for a tire is provided. The bridge patch alters the magnitude, direction, or both of the mechanical force exerted by the innerliner of the tire, and in particular alters the stress-strain relationship in order to obtain the desired stress-strain relationship for operating the electromechanical transducer element , the electromechanical transducer element is connected to the bridge element. The bridge patch includes at least one pad configured for attachment to the inner liner of a tire, the bridge element being attached to the pad and not in contact with the tire. In some embodiments, the bridge patch includes a bridge element that is arched and connected to two pads, each pad being located at an end of the bridge element.

Description

technical field [0001] The present invention generally relates to a bridge patch connected to the inner liner of a tire carrying an electrical circuit with electromechanical transducer elements. The bridge patch is configured to apply a mechanical force to the electromechanical transducer element in a predetermined manner as the tire undergoes deformation. Background technique [0002] The incorporation of circuitry into the tire assembly can allow many functions, including pressure monitoring, temperature monitoring, and tracking of identification data and other information. Electromechanical transducer elements such as piezoelectric elements can be used to power the circuit. An electromechanical transducer element converts force applied to it into electrical energy used to operate an electrical circuit. [0003] One method of applying force to electromechanical transducer elements consists in exploiting tire deformation during vehicle operation. Deformation in a tire, f...
