Dual IMU System for Accurate Gastrointestinal Motility Tracking
Ziyao Zhou, Boyan Li, Chenyang Ren +3
Gastrointestinal (GI) motility disorders impair the coordinated movement of food through the digestive tract. The Wireless Motility Capsule was developed to indirectly assess GI mo…
Enhanced-BLE: A Hybrid BLE-ESB Framework for Dynamically Reconfigurable and Energy-Efficient 2.4 GHz IoT Communication
Ziyao Zhou, Chen Shen, Tiancheng Cao +1
Bluetooth Low Energy (BLE) is widely used in IoT systems because of its low power consumption, interoperability, and reliable bidirectional communication. However, its connection-o…
Kirigami-Structured Electronic Capsule for Long-Term Continuous Gastric Monitoring
Hen-Wei Huang, Claas Ehmke, Dawei Wang +14
Ingestible electronic systems enable non-invasive, in situ sensing within the gastrointestinal (GI) tract, yet clinical translation has been limited by uncontrolled transit, short…
Multiprotocol Wireless Timer Synchronization for IoT Systems
Ziyao Zhou, Tiancheng Cao, Chen Shen +3
Accurate time synchronization is essential for Internet of Things (IoT) systems, where multiple distributed nodes must share a common time base for coordinated sensing and data fus…
Enhanced ShockBurst for Ultra Low-Power On-Demand Sensing
Ziyao Zhou, Chen Shen, Sicong Shen +1
On demand sensing is emerging as a key paradigm in Internet of Things (IoT) systems, where devices remain in low power states and transmit data only upon event triggers. Such an op…
Reevaluating Bluetooth Low Energy for Ingestible Electronics
Ziyao Zhou, Zhuoran Sun, Xinyi Shen +4
Bluetooth Low Energy (BLE) has been widely adopted in wearable devices; however, it has not been widely used in ingestible electronics, primarily due to concerns regarding severe t…
