The paper “Low-cost gastrointestinal manometry via silicon-liquid-metal transducers resembling a quipu” was published in Nature Biomedical Engineering on March 21, 2022, by Dr. Nan Kewang’s team. It describes the development by Dr. Nan et al. of a simple, low-cost, and easily fabricated catheter device that can be used to capture dynamic pressure changes observed in the human gastrointestinal tract and thus serve as a primary diagnostic basis for gastrointestinal motility disorders.

The TruEbox 01RC from LinkZill helps Dr. Nan’s team to detect the data of each channel in the band pressure measurement device in an affordable and timely manner in various experimental sites. The pressure-sensing capability of the system under various conditions was verified through in vitro testing. Further evidence of the potential clinical utility of the system was demonstrated by using the device to study simulated esophageal dynamics. The potential clinical utility of the system was further demonstrated by comparison with commercially available EndoFLIP and high-resolution manometry (HRM).

Dr. Nan Kewang of MIT said: We are satisfied with the performance of TruEbox 01RC in this project, especially its high sampling rate, high signal-to-noise ratio, compactness and portability, no external power supply, etc. We are also impressed by its function of displaying multi-channel data in real-time in the mobile app interface. After introducing the product to post-doctoral colleagues at MIT, they were shocked that the TruEbox 01RC could drive R&D for projects related to sensor development and wearable electronics without any other product close to such cost-effectiveness.
