A smart sensing thread based on a cotton substrate and coating realized from polystyrene and carbon nanoparticles has been developed. Manufacturing method used is an innovative extru-coating procedure developed especially for the purpose. The strain response of the smart sensing thread has been recorded. It has been observed that the sensing thread has a heterogeneous structure along the cross section. This is because of the fact that most of the coating material is deposited at the surface and the sub-surface layer. The core receives the least amount of absorbed solution. This has been confirmed by SEM image analysis and visual analysis of the fracture specimens as well. The dynamic range of the sensor was found to be 11%, while the sensitivity value was calculated to be 15.5. The smart sensing threads are able to detect strains as the electrical resistance changes with strain with a rather high gauge factor and can be used for various sensing applications as strain gauges and flexible sensors. © 2016 IEEE.

With the aging population increasing, the Osteoporosis (OP) in aging people is rising, and it has an important significance to take the prevention and treatment of osteoporosis as a way to improve the health quality of the elderly. The research presents an osteoporosis calcaneus bone test device, which designs two ultrasonic probes for test the bone mineral density (BMD), one transmitting probe for sending the ultrasonic signal and the other, received probe, for collecting the ultrasonic attenuates detecting signal pass through bone, also the both probes are designed as a same kind probe for ultrasonic transmitting and receiving selection. © Springer International Publishing Switzerland 2014.
