Hybrid and Passive Tissue-Anchoring Mechanism for Ingestible Resident Devices

This work presents a hybrid tissue-anchoring mechanism that combines a pre-compressed microspring for autonomous actuation and a barbed microneedle (MN) for robust tissue anchoring with minimized preloading. The spring-microneedle unit (SMU) allows facile integration with potential ingestible reside...
