Ingestible capsule uses light-emitting bacteria to monitor gastrointestinal health

Ultra-low-power device in gut wirelessly transmits diagnostic signal to a cell phone; multiple gastrointestinal diagnoses possible
May 28, 2018

A sensor capsule that can be swallowed uses light-emitting, genetically engineered bacteria (right) to detect molecules that identify bleeding in the stomach or other gastrointestinal problems. Ultra-low-power electronics (left) sense the light and send the diagnostic information wirelessly to a cellphone. An Android app then analyzes the data. (credit: Lillie Paquette/MIT)

Self-healing material mimics the resilience of soft biological tissue

Imagine first-responder robots that instantly heal themselves when damaged, or wires that continue to conduct electricity when cut
May 21, 2018

A self-healing material that spontaneously repairs itself in real time from extreme mechanical damage, such as holes cut in it multiple times. New pathways are formed instantly and autonomously to keep this circuit functioning and the device moving. (credit: Carnegie Mellon University College of Engineering)

MIT’s modular plug-and-play blocks allow for building medical diagnostic devices

Small labs around the world will be able to cheaply and easily detect diabetes, cancer, and infectious diseases such as Zika virus
May 16, 2018

Tiny 1/2-inch low-cost “Ampli blocks” can be assembled to create diagnostic devices. The blocks, which simply consist of a tiny sheet of paper or glass fiber sandwiched between a plastic or metal block and a glass cover, snap together to form a diagnostic procedure. Some of the blocks contain channels for samples to flow straight through, some have turns, and some can receive a sample from a pipette, or mix multiple reagents (chemicals) together. The blocks are color-coded by function, making it easier to assemble pre-designed devices using instructions that the researchers plan to put online. (credit: MIT Little Devices Lab)
