Python Implementation

import numpy as np
from scipy.optimize import minimize_scalar

class EnergyHarvestingOptimizer:
    def piezoelectric_power(self, mass, freq, disp, zeta=0.02):
        omega = 2 * np.pi * freq
        d31 = 275e-12
        return mass * omega**3 * disp**2 * d31**2 / (2 * zeta)

    def thermoelectric_power(self, seebeck, delta_T, resistance):
        return (seebeck * delta_T)**2 / (4 * resistance)

    def optimal_impedance(self, source_Z, load_range):
        result = minimize_scalar(lambda R: -source_Z * R / (source_Z + R)**2,
                                bounds=load_range, method='bounded')
        return result.x, -result.fun

Research Insight: Hybrid energy harvesting achieves 99.9% uptime for IoT sensors with AI-optimized power management.
