ViPSN (acronym of vibration-powered sensing node) is a programmable Internet of Things (IoT) platform for the development of vibration- or motion-powered sensing and transmitting systems. It serves as a reconfigurable developing platform for vibration-powered IoT applications. The whole set of ViPSN assembles six basic modules: a vibration emulator as the energy generation unit (EGU); a piezoelectric transducer as the energy transduction unit (ETU); a power-boosting interface circuit as the energy enhancement unit (EEU); a dc-dc regulator with energy-level indicating signals as the energy management unit (EMU); a Bluetooth low energy (BLE) module as the energy user unit (EUU); and a mobile app as the edge demonstration unit (EDU). All units or modules are connected with easy mechanical joggle joints and electrical plunger pin contacts.
Coming soon! Right now we are working on a way to get hardware to people, please contact the authors for more information. For now, feel free to explore the hardware and software designs.
- Altium Designer (version 16.1 or above) is used for the PCB design.
- Solidworks(version 2018 or above) is used for 3D-printer case.
- Keil5 is required to compile the software.
