background: in this work investigation of the normoxic pagat polymer gel dosimeter such as sensitivity, the r2-dose response with post time and the percentage depth dose (pdd) of pagat polymer gel dosimeter have been undertaken. materials and methods: using mri, the formulation to give the maximum change in the transverse relaxation rate r2 was determined to be 4.5% n,n'-methylenbis- acryl...

Microfluidic chips are powerful tools for biochemical experiments. High speed and precise flow control can be achieved by using microvalves on a chip. Several types of microvalves that can be integrated into a microfluidic chip have been reported. Among them, gel microvalves have certain advantages over other valves because of their soft structure, which will contribute to prevent mechanical da...

This paper proposes a model for predicting dynamic motions of elastic robots made entirely of electro-active polymer gel. The requirement is that both active and passive deformations be described simultaneously. Active deformations arise from generated stress, while passive deformations are due to external forces, such as gravity and friction. We represent both in the same framework, considerin...
