Abstract

A self-powered electrochromic supercapacitor includes a nano-generator (a), a rectifier (b) and an electrochromic supercapacitor (c), wherein the anode electrode (1) and the cathode electrode (3) of the nano generator (a) are respectively connected with the AC input terminal of the rectifier (b), and the DC output terminal of the rectifier (b) is respectively connected with the transparent anode electrode (4) and the transparent cathode electrode (7) of the electrochromic supercapacitor (c) to form a complete circuit. The self-powered electrochromic supercapacitor can achieve collection-conversion-storage-application of energy from human body, can collect energy when a human body moves and then utilizing an electrochromic supercapacitor (c) to store the energy after the energy is converted, which can be used for monitoring and collecting physiological signals of a human body without external energy supply, and can be used in combination with wearable equipment for monitoring human bodyhealth.

Description

technical field [0001] The invention relates to a self-powered electrochromic supercapacitor, which belongs to the field of electrochemistry. Background technique [0002] In the past few decades, with the improvement of science and technology and the development of medical technology, intelligent, miniaturized and integrated portable wearable sensors have developed rapidly, and have become a research hotspot in the field of sensors. Medical care is closely related. Currently, one of the key challenges for the continued development of such wearable sensors is to find suitable sustainable energy systems, while commonly used secondary batteries and recently developed capacitors with high energy density usually have stacked planar porous structures and employ inorganic Active materials are used to prepare electrodes, which is difficult to prepare flexible wearable devices, and the service life of these energy systems is limited, which is easy to cause secondary pollution. The...
