Three materials are commonly used for thermoelectric generators. These materials are bismuth (Bi2Te3) telluride, lead telluride (PbTe) and Silicon germanium (SiGe). Properly utilizing TEG can become a potentially sustainable and renewable energy resource (Elsheikh et al., 2014). Depending on the administration time of Bismuth in the clinic, its toxicity can be roughly divided into acute and chronic exposures. Both exposure doses can cause neurotoxicity, gastrointestinal toxicity, nephrotoxicity, hepatotoxicity, and increased bismuth concentration in blood. Although Bismuth is considered to be non-toxic and as much as 15 g can be tolerated by an adult, the long-term use of Bismuth may result in side effects and even toxicity to human subjects. Bismuth might slow blood clotting. Bismuth and medications that slow blood clotting might increase the risk of bruising and bleeding. 3 Bismuth poisoning mostly affects the kidney, liver, and bladder. Chronic exposure to high levels of bismuth salts results in encephalopathy, whereas acute toxicity manifests as nephrotoxicity. 2 In this case report, we present a 21-year-old woman with chronic renal failure one year after CBS intoxication. It's listed by the FDA as safe and likely nontoxic; however, it does lead to some skin concerns (not to mention it closely resembles the element, Arsenic): Irritation, especially when sweating—itching & Rashes. Bismuth sources affecting the kidneys were uniquely reported for medical purposes and mostly associated with overdoses with several symptoms, apparently with dose-dependent consequences. The patient's history of renal impairment seemed to affect the case outcome. Require a relatively constant heat source. Lack of industry education about thermoelectric generators. Slow technology progression. High output resistance.
