A major issue concerning many adults worldwide is obesity [1]. The goal of this work is to address this problem by designing a novel swallowable microrobotic capsule that will attach a sensor to the lining of the gastrointestinal (GI) tract that will detect mass flow rate. Mass flow rate reflects the food intake and is also important as guide data in drug absorption and hospital patient enteral feeding fields. One problem that arises is creating a long-term attachment to the GI tract that can endure the environment and will not cause damage to the lining. The gastrointestinal wall is irregular, slippery, chemically corrosive, and physiologically active due to peristalsis. No traditional technologies enable an effective clamping on such a surface for prolonged time and without provoking damage or bleeding [2]. As a result of unsuccessful long-term attachment, we have investigated biomimicry. Many species of animals and...
