A group of researchers at the Helmholtz Zentrum München and the Technical University of Munich (TUM) have developed an ultrasound detector, based on silicon photonics and measuring a hundredth the width of a human hair. They claim it is the world’s smallest ultrasound detector. Rami Shnaiderman, developer of the SWED device says: “This is the […]
Ultrasound Patch Can Measure Blood Pressure Deep Inside Body
https://www.electronics-lab.com/ultrasound-patch-can-measure-blood-pressure-deep-inside-body/
via Wearable Technology Scientists at the University of California San Diego created a new wearable ultrasound patch that non-invasively monitors blood pressure in arteries deep beneath the skin such as the jugular vein and carotid artery. The new patch could be helpful in detecting cardiovascular problems earlier on and with greater precision. In a proof-of-concept […]

Anfractuosity published a new project: “Acoustic cryptanalysis is a type of side channel attack that exploits sounds emitted by computers or other devices” Wavecatcher is a simple PCB that makes use of a MEMS ultrasound microphone, in order to capture audio to around 80kHz, with the goal of finding interesting ultrasound sources and playing with […]
Butterfly IQ – Ultrasound Anywhere, Anytime
https://www.electronics-lab.com/butterfly-iq-ultrasound-anywhere-anytime/
Ultrasound, also known as sonography, is a medical procedure which uses sound waves to get images from inside the body. It is used to help guide biopsies, diagnose causes of pain, examine a baby in pregnant women, diagnose heart conditions etc. High- frequency sound waves are transmitted to the body using a small transducer (probe), […]
