Ingestible electronic device detects breathing depression in patients

The new sensor measures heart and breathing rate from patients with sleep apnea and could also be used to monitor people at risk of opioid overdose.

An implantable device could enable injection-free control of diabetes

The device contains encapsulated cells that produce insulin, plus a tiny oxygen-producing factory that keeps the cells healthy.

Wearable patch can painlessly deliver drugs through the skin

Using ultrasonic waves that propel drug molecules into the skin, the patch could be used to treat a variety of skin conditions.

Ingestible sensor could help doctors pinpoint GI difficulties

The sensor sends out its location as it moves through the GI tract, revealing where slowdowns in digestion may occur.

Magnetic sensors track muscle length

Using a new technology, researchers hope to create better control systems for prosthetic limbs.

Engineers boost signals from fluorescent sensors

The advance allows the particles to be placed deeper within biological tissue, which could aid with cancer diagnosis or monitoring.
