Abstract
Here we detail our progress in developing the infrastructure for traceable transient measurements of pressure and temperature. Towards that end, we have built and characterized a dual diaphragm shock tube that allows us to achieve shock amplitude reproducibility of 2.3%. In this proof-of-concept study we use our shock tube to characterize the dynamic response of photonic sensors embedded in polydimethylsiloxane (PDMS), a material of choice for soft tissue phantoms. Our results indicate the PDMS embedded photonic sensors response to shock evolves over tens to hundreds of microsecond time scale making it a useful system for studying transient pressures in soft tissue.Citation
