Several researchers have compared the performance of a standalone triboelectric and piezoelectric energy harvester operating under very low frequencies (< 5 Hz). However, there have been no reports of comparison between devices designed with the exact same topology and observing the variation in their relative frequency response under varying design parameters and operating conditions. In this paper, we present a comparative study of frequency response of the triboelectric nanogenerators and impact-driven piezoelectric generators. Both these devices are realized as a combination of a cantilever beam and an impact layer. They have a similar operating mechanism in the sense that they involve an impact between a vibrating beam and a rigid impact layer, but the inherent energy generation mechanism in both cases is very different. Due to this, we observe stark differences in the frequency response of these devices at different resonant frequencies and under varying gap lengths and acceleration amplitudes. We have initially explained the basic energy generation mechanism and developed an analytical model for the triboelectric and piezoelectric mechanisms. It is then solved numerically to predict the device operation and validated using device fabrication and experimentation. This is followed by observation, comparison and explanation of their contrasting frequency responses. This study is crucial as it assists in understanding the contrast that exists between the two energy harvesting mechanisms and will hopefully be useful while choosing and designing any piezoelectric/triboelectric device for powering low power wearable sensors from ultra-low frequency, wideband human motions.","PeriodicalId":165158,"journal":{"name":"2021 IEEE 20th International Conference on Micro and Nanotechnology for Power Generation and Energy Conversion Applications (PowerMEMS)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126842606","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Enabling WBAN nodes to be fully autonomous is critical in making this thrust sustainable. However, regular charging of batteries in such systems remains a significant inhibitive factor. In this work, Health Monitoring Energy System (HeMeS) tool previously developed by our group using comprehensive analytical models is utilized to study various energy flow scenarios in a particular health monitoring WBAN node powered by a hybrid thermal-vibrational energy harvester. The use of HeMeS for design space exploration is thus demonstrated for various patient categories, incorporating environmental factors, electronic load activity levels, and system cost/size constraints. The described comprehensive system design approach of incorporating transducer, electronics, user environment and data duty-cycling profiles, is demonstrated to be viable and appealing for delivering sustainable WBANs that directly contribute to climate-neutral society without significantly increasing cost.","PeriodicalId":165158,"journal":{"name":"2021 IEEE 20th International Conference on Micro and Nanotechnology for Power Generation and Energy Conversion Applications (PowerMEMS)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127016761","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The unique sliding block-rail piezoelectric generator (S-PEG) is superior as converting three-dimensional (3D) lower-limb motion into one-dimensional (1D) linear sliding on the rail, which further activates the vibration of piezoelectric bimorphs for effective energy scavenging. The particularly designed mechanical structure enables to achieve a high-power output of 2.4mW at an extremely low operating frequency (0.75Hz) and reach to 160μC/s of the charging speed on a 1mF capacitor. Moreover, we demonstrate the feasibility of the S-PEG on the lower limb acts as an auxiliary battery to supply the wireless transmission modules for diversified applications. In addition, the capability of the S-PEG is displayed as a practical power source for wearable sensors of low-power Bluetooth temperature and humidity modules. Moving forward to the Internet of Things (IoT) framework, the S-PEG is able to become a promising candidate in the sustainable energy sources to further extend the lifetime of the wearable sensors.","PeriodicalId":165158,"journal":{"name":"2021 IEEE 20th International Conference on Micro and Nanotechnology for Power Generation and Energy Conversion Applications (PowerMEMS)","volume":"150 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114210074","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper proposes a self-tuning stochastic resonance for exploring its principle for further stabilizing the sustainable capability of energy harvesting. The principle of stochastic resonance of a nonlinear system in a rotating environment is studied which is used to increase the energy harvesting efficiency of the cantilever piezoelectric vibrator at low frequencies. The centrifugal force caused by the behavior of ration acting on the end mass of the cantilever changes the equivalent stiffness of the cantilever and thus can tune the stochastic resonance frequency. Through the match-able relationship of non-linear bitable system between the Kramers rate and the external rotation frequency, the optimal centrifugal distance is theoretically obtained. The simulation results show that when the centrifugal distance is 12.11 cm, the effective frequency bandwidth of the system response is broadened to 20–40 rad/s and the output root mean square (RMS) voltage is significantly improved.","PeriodicalId":165158,"journal":{"name":"2021 IEEE 20th International Conference on Micro and Nanotechnology for Power Generation and Energy Conversion Applications (PowerMEMS)","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125190177","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
