Abstract
Miniaturized wearable or implantable medical sensors (or actuators) are often used in the Internet of Things (IoT) technologies in healthcare applications. However, their limited source of power is becoming a bottleneck for the pervasive use of these devices, especially, as their functionality increases. Kinetic-based micro-energy harvesters can generate power through the natural human body motion. Therefore, they can be an attractive solution to supplement the source of power in medical wearables or implants. The architecture based on the Coulomb force parametric generator (CFPG) is the most viable micro-harvester solution for generating power from human motion. This article proposes three methods: a linear estimation approach, a multi-armed bandit algorithm, and a min–max-based approach to adaptively estimate the desirable electrostatic force in a CFPG using the input acceleration waveform. Through extensive simulations, the performance of the proposed methods in maximizing the output power of the micro-harvester is evaluated.
