Abstract: This device employs 3D and/or 2D magnetic field measurement sensors and an array of magnets embedded in the tire, to provide information regarding the shear strain induced in tire at the contact area between the tire and the road by friction and compressive strain in the tire due to vertical load applied on the tire, and the data is transmitted wirelessly to a receiver. The device is an ultra-low power, one-way communication, magnetic tire monitoring multi-sensor system, a microprocessor, a signal amplifier, signal filtering, using error correction algorithms, an analog-to-digital converter and a wireless electromagnetic data transmitter to transmit to a remote receiver for further processing, using a computer network and wireless access points in fixed locations. The collected data is then employed to measure the real time friction coeffcient between the tire and the road during rotation of the tire when the sensor is in contact with the road.
