Blind Cave Fish-inspired Sensor to Regulate IVs

(L-R) Blind cave fish has an uncanny ability to swim adeptly at high speeds underwater without colliding into any surrounding objects. Protruding outside its entire body are hundreds of neuromasts (lateral line system) that detect movement and pressure changes in the surrounding water. Inspiration from this fish has led to the development of these ultra-sensitive, high resolution, low-cost, miniaturised, zero-powered sensors that is the size of a mere speck on a Singapore 5-cents coin.

Inspired by the blind cave fish, researchers at the Singapore-MIT Alliance for Research and Technology (SMART) [新加坡-麻省理工学院科研中] have developed Micro-Electro-Mechanical Systems (MEMS) flow sensor so tiny and sensitive that it can be implanted into the IV or intravenous set-up, to aid in regulating the velocity of the fluid flow with minimal intervention by the nurses, thereby reducing their workload while increasing their productivity by 30%; and significantly decreasing the complications of drug infusion via IV therapy. These sensors can also be incorporated into marine underwater robots, lending them sensitivities to wakes, akin to the blind cave fish itself, so that the robots can manoeuvre in a highly energy-efficient manner.
