Abstract

This paper provides an energy-harvesting, shoe-mounted system for medical sensing using piezoelectric transducers for generating power. The electronics are integrated inside a conventional consumer shoe, measuring the pressure of the wearer's foot exerted on the sole at six locations. The electronics are completely powered by the harvested energy from walking or running, generating 10-20 μJ of energy per step that is then consumed by capturing and storing the force sensor data. The overall shoe system demonstrates that wearable sensor electronics can be adequately powered through piezoelectric energy-harvesting.

摘要

本文提供了一种用于医学传感的能量收集式鞋载系统，该系统使用压电换能器来发电。电子器件集成在传统的消费级鞋子内部，可在六个位置测量穿戴者施加在鞋底上的足部压力。电子器件完全由行走或跑步时收集的能量供电，每走一步可产生10 - 20微焦耳的能量，这些能量随后用于采集和存储力传感器数据。整个鞋类系统表明，可穿戴传感器电子器件可以通过压电能量收集得到充足的供电。
