3 What is energy harvesting? Vibration Electrical PowerWireless condition monitoring of equipment
4 Microgenerator concept Unlimited energy from ambient vibrationFully enclosed unlike wind, solar etc.MassSuspensionTransducer
5 Application: condition monitoring 1. To identify failure (diagnosis)No signalOvertemperature2. To identify impending failure (prognosis)DowntimeAccident preventionConsequential damage3. To know why failure occursPull the machine from serviceAnalyse the incipient failureChange what you’re doing
