This study proposes a separate and combined (pyroelectric + piezoelectric) energy harvesting system using bimetallic beam. Hybrid is achieved by waste thermal expansion mismatch of the In this regard, four types design are proposed, along with various heating/cooling cycles. Auxetic layers in beam used to enhance power. The best‐performing cycle considered for further power increment. Two models simulated based on low (model C3) high heat consumption C5). load resistance, frequency, pyroelectric/piezoelectric layer thickness varied maximum obtained at 175 MΩ (C3), 75 (C5), 0.02 Hz (C3 C5) 0.4 mm as 20 μW (C3) 40 μW(C5), respectively. piezoelectric, pyroelectric variation effect stress temperature fluctuations H‐PEH layer. Additionally, five well‐known higher coefficient materials studied found that La‐NBT‐BT‐Ta gives 0.811 1.99 mW (C5) model, generated both analyzed look practical feasibility.
