Michelin Recherche et Technique S.A.

International Classification:

G01M 1702

US Classification:

731465, 73146

Abstract:

A system for generating electric power from a rotating tires mechanical energy concerns a power generation device with a piezoelectric structure and an energy storage device. The piezoelectric structure preferably comprises a plurality of piezoelectric fibers embedded in a generally unidirectional fashion within an epoxy matrix. The piezoelectric structure may be mounted on a support substrate that helps distribute mechanical strain to which the piezoelectric fibers are subjected in a substantially uniform fashion. The piezoelectric structure is preferably mounted within a tire structure such that electric charge is generated therein as the wheel assembly moves along a ground surface. Electrode layers within the piezoelectric structure are coupled to a power conditioning module that rectifies the resultant electric current from the piezoelectric structure and stores it in an energy storage device, preferably an electrolytic capacitor. A rechargeable battery may also be provided for storing additional charge generated within the piezoelectric structure. A regulated voltage source is provided from the energy stored in the power generation device and can be used to power various electronics systems integrated within a tire or wheel assembly.

10/374936

Inventors:

John David Adamson - Simpsonville SC, US
George Phillips O'Brien - Piedmont SC, US

Assignee:

Michelin Recherche et Technique S.A. - Route Louis-Braille

International Classification:

G01M 1702

US Classification:

290 1R, 1521521

Abstract:

A power harvesting solution concerns a generally non-conductive tire structure that is formed with at least one defined conductivity path through which static electricity accumulated in the tire structure during tire rotation can dissipate to ground. Such conductivity path is formed from a portion of conductive material that may be partially surrounded by additional insulative material to restrict the flow of electric charge to ground. An energy storage device, such as a capacitor or rechargeable battery, is coupled with the conductivity path and configured to store selected amounts of the electric charge dissipating through the conductivity path. Various diode elements may be provided in combination with the energy storage device to prevent reverse discharging of and to provide voltage protection for the energy storage device. Sufficient accumulations of such harvested energy can then power tire electronic systems, including various condition-responsive devices (i. e. , sensors, etc.

International Classification:

G01M 17/02

US Classification:

73146, 307 44

Abstract:

A tire assembly with integrated power generation features includes one or more piezoelectric devices and power conditioning modules. Piezoelectric devices may include a plurality of piezoelectric fibers embedded in a generally unidirectional fashion within an epoxy matrix, a piezoceramic wafer provided on a substrate and substantially surrounded by a protective casing, or a piezoceramic unimorph structure adhered with a thermoplastic polyimide to respective top and bottom conductive layers. Each piezoelectric device may include multiple piezoelectric elements connected in series and/or parallel arrangements, configured with respective poling directions in opposing or in-phase arrangements and/or configured in d33 or d31 displacement modes. Piezoelectric devices are preferably mounted within a tire or wheel assembly such that electric charge is generated therein as the wheel assembly moves along a ground surface and is subsequently stored in one or more energy storage devices. Stored energy may then be used to power electronics such as a tire monitoring system that wirelessly transmits such information as tire pressure, temperature and identification variables to a remote receiver location.

Abstract:

A piezoelectric triggering mechanism () includes a piezoelectric element (), such as the transducer of a SAW device, that is configured to crack or break upon being subjected to excessive levels of mechanical force or other triggering mechanisms, thus generating a burst of electromagnetic energy. The large impulse of energy can then be conditioned () through resonant circuits or antennas and modulated () with an identification pattern through appropriate structures (such as SAW electrodes) to send a breakage indication signal to a remote receiver (). Piezoelectric elements () may be integrated with a pneumatic tire structure to provide indication upon pressure loss or tire failure. Piezoelectric elements () may also be integrated with safety support features of some tire structures to provide indication of tire operation in a run-flat mode of operation. Related aspects of the present piezoelectric triggering technology employ a piezoelectric element () in a trigger detection method, which may involve detection of such occurrences as breach of security via opening of a sealed access structure or breakage of a glass panel, deployment of an airbag, loss of pressure or excess deflection in a tire, presence of smoke in a given location, and other rupture and sensor applications.
