Dr. Sagar M. Doshi. Dr. Doshi completed his Ph.D. defense in spring 2020 in the Department of Mechanical Engineering and the Center for Composite Materials at the University of Delaware. His research focuses on processing and characterization of nanomaterial-based hierarchical composites. Doshi has collaborated extensively with researchers from Civil Engineering, Biomechanics and Electrical Engineering to develop novel solutions for structural health monitoring of civil infrastructure and low-cost wearable sensors for human motion analysis and has been cited numerous times (Google Scholar: >207 citations, h-index: 6, i10-Index: 5).

Metal structures exposed to cyclic loading, including aerospace structures, bridges, and vibrating machinery, are susceptible to fatigue cracking. Monitoring fatigue cracks in metal structures is thus critically important for preventing failure by making repair decisions before a crack reaches its critical length, leading to fracture.

Metal structural components of aircraft, machines, vehicles, and infrastructure deteriorate over their service life due to static and cyclic loading, exposure to corrosive chemicals, and harsh environments. For example, steel bridges are particularly susceptible to fatigue cracking as increased traffic demands often exceed their design load capabilities and members often have fatigue-sensitive details. Corrosion due to deicing chemicals can also result in deterioration and reduction in load-carrying capacity. The result is progressive weakening of the structural elements due to section loss and cracking.
The average yearly costs of US pipeline incidents increased to approximately $733M/yr from the period of 2016-20, an increase over the previous five years. These hazards represent significant costs in terms of personal injury (2,000-4,000 injuries/yr in the US Oil & Gas industry), environmental damage, and monetary losses due to fines, cleanups, and system shutdowns that can approach $1M/day.
There are about 345,000 Achilles Heel and over 1M ankle injuries every year. In many of these injuries, a brace is fitted on the patient with instructions to "self monitor" the weight that they put on that joint- the "toe touch weight bearing." Patients are often confused about "% of weight" to keep off their ankle, and there is no way for the medical professional to monitor these recommendations and inform the patient if he or she is properly adhering to these instructions.
MCET technology can do this and both alert the patient and the medical professional if the instructions are being followed properly.
