When a pacemaker's battery gets low, the whole implant typically has to be surgically replaced. Scientists are therefore developing a noninvasive battery recharging system, which utilizes externally ...

Ultrasound neuromodulation, as a technique for controlling neural activity, has garnered increasing attention in recent years. However, when transmitted externally, ultrasound encounters significant ...

A new way of creating specially shaped pulses of ultrasound using light and a 3D printer has been unveiled by Michael Brown and colleagues at University College London. The pulses, which are creating ...

A digital ultrasonic generator from Herrmann Ultrasonics Inc. enables a user to weld, bond and seal larger thermoplastic parts than a previous digital-signal-processor series allowed. Over two years, ...

(HealthDay News) – A commercially available therapeutic ultrasound generator and transducer can reduce sperm counts in male rats to levels which would result in infertility in humans, according to a ...

Ultrasound is an established way to image biological tissues, traditionally using arrays of electronic transducers to both generate and receive the ultrasonic signals. An all-optical variant of the ...

Fiber-generated ultrasound technologies have been widely used in medical and industrial areas. In spinal fusion surgeries, over 20% of the patients suffer from screw misplacement. The orthopedic spine ...
