Abstract: The Cone Penetrometer Technology (CPT) has evolved over the last several decades as a low cost technique for performing subsurface evaluation for environmental and structural interest. The basic CPT system consist of the push system, cone module, pushrods, tether cable and the data acquisition system. The tether cable is the communication and power interface between the cone and the acquisition system. The Wireless Magnetic Mutual Induction system will replace the need for the tether cable by implementing a battery pack and a wireless communication scheme by using the pushrods, specially made solenoids, and by applying the principle of mutual induction and Faraday's Law.
