“…In this paper, a novel folding scheme is proposed for the thin-film thermoelectric generators with the heat flux and electrical current parallel to the film surface but the temperature gradient perpendicular to the plane of the TE module. Different from the previously reported corrugated thermoelectric generators [21][22][23][24][25], the 0 proposed folding enables a high packing density for the thermoelectric elements without compromising the thermal contact area to the heat source and sink. It also enables the application of only single conductiontype semiconductors as the TE materials and, thus, provides a possibility to simplify the manufacturing process and to avoid the usage of the lower quality TE materials in the module.…”

“…Unfortunately, this seems to be the case even when reporting on the thin-film TE devices with the current flow in the plane of the thin-film. The fact that the electrical resistance may become very high in the TE modules consisting of several such thin-film TE units connected electrically in series, is usually well recognized [5,23,32]. However, the significance of the available electrical current is typically not discussed in the reports, even though the produced current may be too small for practical applications, especially under modest temperature gradients [18,19,[21][22][23][24][25]27].…”

Thin-film thermoelectric generators with a novel folding scheme are proposed for large-area, low energydensity applications. Both the electrical current and heat transfer are in the plane of the thermoelectric thinfilm, yet the heat transfer is across the plane of the modulesimilar to conventional bulk thermoelectric modules. With such designs, the heat leakage through the module itself can be minimized and the available temperature gradient maximized. Different from the previously reported corrugated thermoelectric generators, the proposed folding scheme enables high packing densities without compromising the thermal contact area to the heat source and sink. The significance of various thermal transport, or leakage, mechanisms in relation to power production is demonstrated for different packing densities and thicknesses of the module under heat sink-limited conditions. It is shown that the power factor is more important than ZT for predicting the power output of such thin-film devices. As very thin thermoelectric films are employed with modest temperature gradients, high aspect-ratio elements are needed to meet theusually ignoredrequirements of practical applications for the current. With the design trade-offs considered, the proposed devices may enable the exploitation of thermoelectric energy harvesting in newlarge-areaapplications at reasonable cost.

“…[10] the authors reported some details about the design and fabrication of a wearable and flexible thermoelectric generator. The proposed TEG was designed to be used as "electronic garment", in order to recover the heat useful to the thermoelectric generation from the temperature difference existing between the body skin and the environment.…”
