“…To detect those variations a technique applied in structural health monitoring (aerospace, civil and mechanical engineering) can support the idea of detecting changes in stiff biological structures like bone. Different studies have shown a truly opportunity to implement the EMI technique in bone monitoring [7][8][9]. We see a challenge to achieve that those techniques permit in a short term to monitor BMD frequently the bone without affect the human health.…”

“…The diagnosis of a fully healed bone fracture is critical for making the best management decisions, but various studies have revealed that there is no standard diagnostic technique in this field [ 3 – 5 ]. Radiography and physical examination are two popular approaches for monitoring the healing process of bone fractures used in medical centers [ 6 ]. Radiographs are taken during the beginning of bone lengthening, the end of the distraction phase, and the beginning of bone union (consolidation or device removal phases).…”

“…X-ray radiography is a common approach for identifying bone fractures that exposes a patient to higher quantities of radiation, especially if the patient must be examined multiple times. These tests are extremely harmful to children, pregnant women, and the elderly, not to mention quite expensive [ 6 , 8 , 9 ]. Computed Tomography (CT), Dual Energy X-ray Absorptiometry (DXA/DEXA), and ultrasound can all be used to diagnose bone fractures, but their use in medical centers is limited due to their high cost and radiation exposure [ 7 , 10 ].…”

The most common technique of orthopedic surgical procedure for the correction of deformities is bone lengthening by “distraction osteogenesis,” which requires periodic and ongoing bone assessment following surgery. Bone impedance is a noninvasive, quantitative method of assessing bone fracture healing. The purpose of this study was to monitor bone healing and determine when fixation devices should be removed. The left tibia of eight male New Zealand white rabbits (2.4 ± 0.4 kg) undergoing osteotomy was attached with a mini-external fixator. The bone length was increased by 1 cm one week after surgery by distracting it 1 mm per day. Before and after osteotomy, as well as every week after, bone impedance was measured in seven frequency ranges using an EVAL-AD5933EBZ board. Three orthopedic surgeons analyzed the radiographs using the Radiographic Union Scale for Tibial (RUST) score. The Kappa Fleiss coefficient was used to determine surgeon agreement, and the Spearman rank correlation coefficient was used to find out the relationship between impedance measurements and RUST scores. Finally, the device removal time was calculated by comparing the bone impedance to the preosteotomy impedance. The agreement of three orthopedic surgeons on radiographs had a Fleiss’ Kappa coefficient of 49%, indicating a moderate level of agreement. The Spearman rank correlation coefficient was 0.43, indicating that impedance and radiographic techniques have a direct relationship. Impedance is expected to be used to monitor fractured or lengthened bones in a noninvasive, low-cost, portable, and straightforward manner. Furthermore, when used in conjunction with other qualitative methods such as radiography, impedance can be useful in determining the precise time of device removal.

“…EMI evaluated the feasibility of the technique when bone was modified by different controlled conditions as crack existence, fractures and density variations. In other applications for bone, [14] presented an experimental study to detect a simulated healing process by applying the EMI technique. The applied methodology consisted in putting a healing agent in particular cracks in an isolated bone to be monitored by a PZT-needle sensor.…”

This study exposes the assessment of a piezo-actuated sensor for monitoring elastic variations (change in Young’s modulus) of a host structure in which it is attached. The host structure is monitored through a coupling interface connected to the piezo-actuated device. Two coupling interfaces were considered (an aluminum cone and a human tooth) for the experimental tests. Three different materials (aluminum, bronze and steel) were prepared to emulate the elastic changes in the support, keeping the geometry as a fixed parameter. The piezo device was characterized from velocity frequency response functions in pursuance to understand how vibration modes stimulate the electrical resistance through electrical resonance peaks of the sensor. An impedance-based analysis (1–20 kHz) was performed to correlate elastic variations with indexes based on root mean square deviation (RMSD) for two observation windows (9.3 to 9.7 kHz and 11.1 to 11.5 kHz). Results show that imposed elastic variations were detected and quantified with the electrical resistance measurements. Moreover, it was demonstrated that the sensitivity of the device was influenced by the type of coupling interface since the cone was more sensitive than the tooth in both observation windows. As a final consideration, results suggest that bio-structures (fruits and bone, among others) could be studied since these can modify naturally its elastic properties.
