Abstract

The invention discloses a human body motion energy harvesting-based heart rate measurement device, which comprises an energy management circuit module, a constant-current source chip, a sensor array patch, a signal processing and display module and four energy harvesting modules, wherein the four energy harvesting modules convert mechanical energy generated by human body motion into electric energy and transmit the electric energy into the energy management circuit module; the constant-current source chip is electrically connected with the energy management circuit module and transmits milliampere-scale current to the sensor array patch; the sensor array patch is electrically connected with the signal processing and display module; meanwhile, the sensor array patch transmits a sensor signal to the signal processing and display module; and the signal processing and display module acquires a heart rate signal of a user according to the received sensor signal and displays the heart rate signal to the user through a display screen in the signal processing and display module. According to the human body motion energy harvesting-based heart rate measurement device, the energy harvestingand converting efficiency is improved, so that self-powering of the heart rate measurement device is achieved, and the manufacturing cost is greatly reduced.

Description

technical field [0001] The invention relates to the field of storage battery technology, in particular to a heart rate measurement device and a measurement method based on human body motion energy collection. Background technique [0002] With the rapid development of personal electronics and sensor networks, instruments and equipment in various application scenarios have higher and higher requirements for the portability and battery life of power supplies. As the largest and heaviest component in modern mobile electronics and IoT units, batteries require regular recharging due to their limited lifespan, leading to inevitable design trade-offs between battery size, weight and sustainability. In order to solve this problem, a technology that converts environmental energy into electrical energy and continuously charges the battery has been developed, and the ubiquitous environmental energy such as mechanical energy and heat energy make this technology have a good development p...
