New viscoelastic measurements using ultrasound can be performed. The viscoelasticity of liquids, solids, bulk, and surfaces can be measured. It is particularly effective for analyzing surface degradation and skin layers!
Until now, viscoelastic measurements were generally limited to around 100 Hz, but higher frequencies were desired for actual products. The HFR002 can measure complex viscoelasticity using ultrasonic propagation. All strains propagate at the speed of sound, resulting in overall deformation. Those with significant attenuation are referred to as viscoelastic materials. The storage modulus can be measured at the speed of sound. The loss modulus can be measured from the attenuation. Our proprietary surface method allows for the analysis of surface degradation and the effects of the skin layer, which were previously impossible to assess.

basic information
Measurement Frequency You can switch sensors to measure in the desired frequency range. * Bulk measurement (bottom method) and surface measurement (surface method) can be performed simultaneously on the same sample. Longitudinal Wave Sensor Frequency Range (based on volumetric elasticity) L Sensor: 0.5~2.0MHz M Sensor: 2.0~7.0MHz H Sensor: 5~20MHz In addition, we also have transverse wave sensors capable of measuring based on shear modulus. You can consider matching the challenges and sensors through contracted measurements, so please feel free to contact us for consultation.

Company information
High Frequency Viscoelastic Co., Ltd. primarily focuses on a new technology that enables the measurement of "viscoelasticity," a representative physical property of soft materials such as rubber, at room temperature in the range of 1 to 20 MHz, which has not been widely adopted until now. We are also considering applications for the aging deterioration of polymer materials and improvements in impact strength. Currently, we are selling measurement evaluation devices and providing contract measurements as tools to support the application and expansion of high-frequency viscoelastic technology. We offer new perspectives that have not been available before by applying our technology to various customer challenges. Additionally, leveraging our experience in mechatronic equipment development, high-performance component development, and measurement instrument development, we support business revitalization and new business areas.
