  • Triboelectric Nanogenerator Enabled Body Sensor Network for Self-Powered Human Heart-Rate Monitoring
    ACS Nano, 2017
    Co-Authors: Zhiming Lin, Keyu Meng, Zhihao Zhou, Xiaoshi Li, Jin Yang, Jun Chen, Wei Wei, Zhong Lin Wang
    Abstract:

    Heart-rate monitoring plays a critical role in personal healthcare management. A low-cost, noninvasive, and user-friendly heart-rate monitoring system is highly desirable. Here, a self-powered wireless body sensor network (BSN) system is developed for heart-rate monitoring via integration of a downy-structure-based triboelectric nanogenerator (D-TENG), a power management circuit, a heart-rate sensor, a signal processing unit, and Bluetooth Module for wireless data transmission. By converting the inertia energy of human walking into electric power, a maximum power of 2.28 mW with total conversion efficiency of 57.9% was delivered at low operation frequency, which is capable of immediately and sustainably driving the highly integrated BSN system. The acquired heart-rate signal by the sensor would be processed in the signal process circuit, sent to an external device via the Bluetooth Module, and displayed on a personal cell phone in a real-time manner. Moreover, by combining a TENG-based generator and a TEN...

  • “RANCANG BANGUN KENDALI PERALATAN RUMAH TANGGA BERBASIS SMARTPHONE ANDROID”.
    Fakultas Teknik Universitas Hamzanwadi, 2020
    Co-Authors: Akbar Taufik, Gunawan Indra, Anwar Khairil
    Abstract:

    So far, the community in general can control lights or other electronic equipment with just a switch, but the control is limited by distance. Therefore, the construction of an electronic equipment control system application prototype was built on the Android platform as a new alternative solution for remote control. The application built on the Android platform has an attractive and easy to understand user interface. In addition, the control system built utilizes a Bluetooth network for sending control instructions to Arduino. In this prototype using Arduino Uno as a processor, Android as a control, Bluetooth HC-06 Module as Arduino communication with Android and using relay as a control switch with 4 channel specifications. Communication between an android smartphone and a microcontroller can be done wirelessly using Bluetooth, which the Android smartphone and Bluetooth Module on the microcontroller system can communicate using serial data. The speech recognition feature on an Android smartphone can be used to control the lights using voice commands. This is done by initializing the spectrum of voice commands in the form of strings into character codes that have been identified by the microcontroller. Control of electronic equipment will not work if the Android smartphone is out of range of the Bluetooth wireless transmission range of the Bluetooth Module because the Bluetooth connection will be disconnected automatically

  • Development of the wireless ultra-miniaturized inertial measurement unit WB-4: Preliminary performance evaluation
    Proceedings of the Annual International Conference of the IEEE Engineering in Medicine and Biology Society EMBS, 2011
    Co-Authors: Z. Lin, Luca Bartolomeo, Massimiliano Zecca, Salvatore Sessa, H. Ishii, Atsuo Takanishi
    Abstract:

    This paper presents the preliminary performance evaluation of our new wireless ultra-miniaturized inertial measurement unit (IMU) WB-4 by compared with the Vicon motion capture system. The WB-4 IMU primarily contains a mother board for motion sensing, a Bluetooth Module for wireless data transmission with PC, and a Li-Polymer battery for power supply. The mother board is provided with a microcontroller and 9-axis inertial sensors (miniaturized MEMS accelerometer, gyroscope and magnetometer) to measure orientation. A quaternion-based extended Kalman filter (EKF) integrated with an R-Adaptive algorithm for automatic estimation of the measurement covariance matrix is implemented for the sensor fusion to retrieve the attitude. The experimental results showed that the wireless ultra-miniaturized WB-4 IMU could provide high accuracy performance at the angles of roll and pitch. The yaw angle which has reasonable performance needs to be further evaluated.

  • development of the miniaturized wireless inertial measurement unit wb 4 pilot test for mastication analysis
    IEEE SICE International Symposium on System Integration, 2010
    Co-Authors: Z. Lin, Luca Bartolomeo, Massimiliano Zecca, Salvatore Sessa, H. Ishii, Kazuko Itoh, Atsuo Takanishi
    Abstract:

    Mastication analysis can provide an objective basis for studying and diagnosing jaw musculoskeletal disorders. Therefore, the use and development of devices for quantitatively measuring and analyzing jaw movement have become very popular in the consulting room. This paper proposes a simple to be used jaw tracking prototype by using the new miniaturized wireless Inertial Measurement Unit (IMU) named WB-4. The WB-4 EVTU primarily contains a mother board, a Bluetooth Module and a Li-Polymer battery. The mother board is provided with a microcontroller and 9-axis inertial sensors (miniaturized MEMS accelerometer, gyroscope and magnetometer) to measure the jaw motion. The data transmission between WB-4 and PC is based on the Bluetooth Module to realize the wireless communication. The IMU's extremely reduced weight and size allows it to be easily attached to mandible during normal mastication tests without physical restriction to the subjects. Three pilot experiments for mastication analysis of chewing gum were elaborated. A group of 9 healthy subjects kindly participated in the experiment. The preliminary results show that WB-4 IMU can efficiently evaluate the jaw movement and mastication pattern of different subjects, which could provide quantitative information to the doctors for the diagnosing and clinical treatment of different jaw diseases.
