Nanogenerator-Based Sensors for Energy Harvesting From Cardiac Contraction

Biomedical electric devices provide great assistance for health and life quality. However, their maintainable need remains a serious issue the restricted duration of energy storage. Therefore, scientists are investigating alternative technologies such as nanogenerators that could harvest mechanical human heart to act main source pacemaker. Cardiac contraction is not circulation; it utilizes body an recharge pacemaker devices. This key biomedical innovation protect patients’ lives from possible risks resulting repeated surgery. A batteryless via implantable collecting tool, exchanging restriction current batteries sustainable self-energy resource technique. In this context, physiology in preservation blood distribution pulse generation effects cardiac hormones on heart’s shall be outlined. review, we summarized different harvesters self-powered medical with emphasis nanogenerator-based sensors harvesting contraction. It conclude recent hybrid bio-nanogenerator systems both piezoelectric triboelectric based biocompatible biomaterials clean promising movement. These wearable become tools high efficacy, durability, thinness, flexibility, low cost. Although many studies have proven safety, there long-term biosafety biocompatibility. further note biocompatibility bio-generator addressed.
