Development Of Advanced Solid-State Electrolytes And Interfaces For High-Performance Sulfide-Based All-Solid-State Lithium Batteries, Feipeng Zhao
Electronic Thesis and Dissertation Repository
All-solid-state lithium batteries (ASSLBs) have become increasingly attractive due to the demand of high-energy-density and high-safety lithium-ion batteries for electric vehicles (EVs). As the core component of ASSLBs, solid-state electrolytes (SSEs) are regarded as essential to determine the electrochemical performance of ASSLBs. The inorganic SSEs is one of the most important categories in all developed SSEs, representing the advance of superionic lithium conductors as well as the cornerstone to construct flexible polymer/inorganic composite SSEs. The sulfide-based inorganic SSE is one of the most promising SSEs that is receiving a lot of attentions, because only sulfide SSEs can show ultrahigh ionic …
Development Of A Wireless Telemetry Load And Displacement Sensor For Orthopaedic Applications, William Anderson
Development Of A Wireless Telemetry Load And Displacement Sensor For Orthopaedic Applications, William Anderson
Electronic Thesis and Dissertation Repository
Due to sensor size and supporting circuitry, in vivo load and deformation measurements are currently restricted to applications within larger orthopaedic implants. The objective of this thesis is to repurpose a commercially available low-power, miniature, wireless, telemetric, tire-pressure sensor (FXTH87) to measure load and deformation for future use in biomechanical applications. The capacitive transducer membrane of the FXTH87 was modified, and a relationship was reported between applied compressive deformation and sensor signal value. The sensor package was embedded within a deformable enclosure to illustrate potential applications of the sensor for monitoring load. Finite element analysis was an effective tool to …
Material Property Characterization For Elastomers Within The Framework Of Finite-Deformation Viscoelasticity, Shan Gao
Electronic Thesis and Dissertation Repository
Elastomers are polymeric materials that consist of highly mobile long-molecule chains jointed together through crosslinking. The behavior of elastomers is commonly manifested by hyperelasticity and viscosity due to their molecular structure. Any variation of the material microstructure may have an impact on the macroscopic properties of elastomers. Therefore, characterizing the material properties of elastomers with appropriate constitutive models is essential to facilitating their potential applications. Although various constitutive models have been developed to describe the hyperelastic and viscoelastic behaviors of elastomers, it is still challenging to quantify the material properties of elastomers since there exist restrictions and limitations of the …
