Devices, systems, and methods relating sensing elasticity of biological tissues

Abstract

Described herein are devices, systems, and methods relating to monitoring the elasticity of soft biological tissues, for example, in the gastrointestinal tract. Described herein are embodiments of a wirelessly actuated palpation mechanism integrated into a swallowable capsule device, offering in situ tissue elasticity measurement with minimal invasiveness. Such approach can employ a magnetic soft cantilever beam actuated by external magnetic fields to gently press against soft tissue. Mechanical stress and strain can be monitored by an onboard magnetic sensor and a strain gauge, allowing for accurate assessment of tissue elasticity. Additionally, wireless modules utilizing Bluetooth Low Energy and powered by a battery can facilitate real-time communication. The device and system operates under external magnetic field control, which can move freely over soft tissues during examinations and palpate suspicious areas
