Flexible and wearable sensors are highly desired for health monitoring, agriculture, sport, indoor positioning systems applications. However, the currently developed wireless sensors, which communicated through radio signals, can only provide limited accuracy often ineffective in underwater conditions. In this paper, a platform based on flexible piezoelectric acoustics is with multiple function...

This paper proposes a new tool for the selection of optimal elementary shunts connected to piezoelectric patches, which are bonded on thin structures control multi-resonant flexural vibration produced by broadband stochastic excitations. More specifically, study introduces procedure identification simple shunt architectures composed small-number low-value RLC elements, yet produce significant e...

Breaking reciprocity has recently gained significant attention due to its broad range of applications in engineering systems. Here, we introduce the first experimental demonstration a broadband mechanical beam waveguide, which can be reconfigured represent wave nonreciprocity. This is achieved by using spatiotemporal stiffness modulation with piezoelectric patches closed-loop controller. Using ...

The study aimed at determining the effect of acid modified porcine mucin powder on the release and permeation of insulin in transdermal patches. Various batches of insulin patches were prepared by solvent casting method using polysorbate 80 as emulsifying agent and acid treated and untreated mucin powders as base. The patches were evaluated for their physical properties, folding endurance, moi...

the output of a piezoelectric nanogenerator based on zno nanowire is largely affected by the shape of nanowire. in order to obtain mechanically stable nanogenerator with high performance, the investigation of mechanical and electrical characteristics related to the nanowires and materials used in nanogenerators are of great interest and significance. this paper presents the various behavior of ...
