Rivandi, H. (author), Lopes Marta da Costa, T.M. (author)Ultrasound (US) neuromodulation and ultrasonic power transfer to implanted devices demand novel ultrasound transmitters capable of steering focused ultrasound waves in 3D with high spatial resolution and US pressure, while having a miniaturized form factor. Meeting these requirements needs a 2D array of ultrasound transducers directly...journal article 2023

Xiao, Yidi (author), Rivandi, H. (author), Lopes Marta da Costa, T.M. (author)Emerging ultrasound (US) biomedical applications, from battery-powered US imaging to US neuromodulation, demand wearable form factor and power-efficient US transmitters. Fulfilling these specifications demands a high-frequency and power-efficient 2D US phased-array transmitter directly integrated with the ASIC. In such systems, pulsers are the...conference paper 2023

Rivandi, H. (author), Ghosh, Ishaan (author), Lopes Marta da Costa, T.M. (author)New non-imaging ultrasound applications, such as ultrasound stimulation and ultrasonic power transfer, need sub-millimeter volumetric spatial resolution, electronically control of the focal spot location, high ultrasound intensity, and a tiny form factor. Satisfying these requirements demands a high-frequency phased array ultrasound transducer....conference paper 2022
