This paper reports the heating performance of the previously reported 4 th generation shoe-insole-based hydraulic electromagnetic energy harvester (HEEH) [1] in connection with a micromachined polysilicon heater & a commercial copper heater [2]. The HEEH produced 455.77mW of power by using a 4-channel configuration under an actuation frequency of 3Hz. It was integrated with two types of heaters to produce temperature rises of 2.0 & 3.2°C and the heating rates of 12.0 & 1.6°C/min, respectively, from polysilicon (0.15×0.1mm 2 , 6.05e −6 s of the thermal time constant) and copper heaters (78×28mm 2 , 8.31s of the thermal time constant). Such heating performance of the HEEH is the 1 st results of its kind by energy harvester [3, 4, 5].
