Mapping of Physiological Signals From Wireless Battery‐Free Implants With Plane‐Wave Ultrasound Imaging

Advanced Materials Technologies, Volume 11, Issue 9, 6 May 2026.
Combined approach of electromagnetic (Power) and ultrasound (data harvesting) waves is proposed to address the miniaturized ultrasonic implants. Electromagnetic waves trigger the piezoelectric element to generate the acoustic pulse which is modulated by the variations in the sensor's impedance.

Piezoelectric Polymer Transducers

Advances in Dental Research, 1987
Poly(vinylidene fluoride) (CH2-CF2)n is a tough, flexible polymer readily available in the form of thin film which can be made piezoelectric by the temporary application of a high electric field. The areas of the film which become piezoelectric can be controlled to be the areas where metal electrodes are evaporated onto the film.

Piezoelectric Transducers

Key Engineering Materials, 2013
Piezoelectric materials are used as layers or fibers that are embedded within or bonded to the surfaces of a structure. Piezoelectric transducers can be made in the different shapes. Piezoelectric elements are mainly made of polymer or ceramic materials.

Piezoelectric vibration transducer

The Journal of the Acoustical Society of America, 1984
A piezoelectric vibration transducer is disclosed which includes a polymeric piezoelectric film as the active element. The film is a selectively or fully polarized, uniaxially oriented material selected from the group of polyvinylidene fluoride, blended material such as polyvinylidene fluoride and PZT powder, polyvinyl fluoride, polyacrylonitrile ...
