Disclosed herein are left atrial appendage (LAA) occluders that include self- powered physiological sensors to monitor physiological parameters of a subject. The sensors can be powered by harvesting energy generated by the patient's body or using wireless power delivery technologies. The disclosed devices can be used to close the LAA and to provide self-powering sensors to wirelessly monitor physiological parameters such as heart rate, pressure, temperature, size of the atrium, and levels of biomarkers such as C-reactive protein (CRP) and B-type natriuretic peptide (BNP) (e.g., using biosensors). In addition to addressing the stroke risk for patients with non-valvular atrial fibrillation, the disclosed devices offer post-surgical connected care that can reduce hospital re admissions, provide superior medical management, and improve patient quality of life. 本文公开左心耳(LAA)封堵器，其包括自供电生理传感器以监测受试者的生理参数。传感器可以通过收集患者身体生成的能量或使用无线电力递送技术来供电。所公开的设备可被用于封闭LAA并提供自供电传感器以无线监测生理参数，例如心率、压力、温度、心房尺寸和生物标志物的水平(例如C反应蛋白(CRP)和B型利钠肽(BNP))
