Electronic sensors and various digital devices have been quite successful in improving collection of physical activity data in a pervasive manner, and we believe that advances in dietary assessment can be achieved using similar strategies. Dietary assessment is a critical yet understudied component within the domain of recent advances in electronic health records management. The design of a system...
Lower limb amputees using a prosthetic device often suffer from mechanically-induced skin injuries. Shear stresses are believed to play a significant role in the formation of these skin injuries. The work presented in this paper is aimed at creating a new class of adaptive prosthetic and orthotic interfaces involving a capacitive shear stress sensor. The sensor design and transfer function are discussed...
Deployment of passive RFID systems or RFID-enhanced sensor networks requires good understanding of the energy scavenging principles. This paper focuses on the energy scavenging design considerations of inductively coupled passive RFID systems. The theoretical estimation of the power by an RF antenna is derived, and the effect of the design parameters on the harvested power is investigated. It is shown...
