They generally consist of a microneedle, a microactuator for needle insertion, a blood extraction mechanism and a blood glucose sensor. These devices have great potential to overcome the major disadvantages of several current blood glucose monitoring methods. Over last two decades, extensive research has been made in all of these related fields. More recently, several wearable devices for semi-invasive blood sampling have been developed. This review aims at summarizing the current state-of-the-art development and utilization of such wearable devices for continuous monitoring of blood glucose levels, with a special attention on design considerations, fabrication technologies and testing methods.展开更多

A pill incorporating the technology has been proven to be successful as a weight loss therapy. It enables patients to sustain a diet longer, due to an increase in the level of satiety, resulting in a smaller amount of food intake. Utilization of the technology has recently found new prospects in another organ of the GI tract, the colon. Pseudobezoar technology can be utilized as an enhanced method for colon cancer screening and also as an alternative carrier for bacterial therapy.展开更多

This article evaluates the technique involved in listening to both bowel and stomach sounds and the significance of both normal and abnormal GI auscultation findings. Moreover, intraluminal ultrasonic techniques have been widely used for gastrointestinal disease diagnosis by providing intraluminal images since 1980s, this article also reviews the existing intraluminal ultrasonic technology for diagnosing of GI disorders.展开更多
