A novel energy harvesting system and method utilizing a thermoelectric having a material exhibiting a large thermally induced strain due to a phase transformation and a material exhibiting a stress induced electric field is introduced. A reinforcing filler andor an ethylenealpha-olefin elastomeric copolymer may, optionally, be added during formation of the second blend or in an additional step. By drawing a stroke line in the space, a wall having the stroke line as the base line is set as a canvas. The nodules are adapted to inflate to simulate tumors and are relatively undetectable by touch when deflated. The Multi-Access protocol of the present invention provides a means to connect to multiple endpoints on a single local loop.
