“…However, a long time is required to increase the temperature. Kwon et al (2019) and Rousseaux and Robson (2017) conducted clinical experimental research on RF hyperthermia cosmetic devices available in the commercial market. These studies applied relatively high power to the electrode to generate heat quickly and achieved a temperature increase of approximately 10°C.…”

Radio frequency (RF) hyperthermia focuses on raising the target area temperature to a value exceeding 45°C. Collagen is stimulated when the temperature rises to 45°C at the dermal layer, resulting in skin tightening. However, most studies on RF hyperthermia have focused on tumor ablation or using electrodes to radiate an electromagnetic field, which is highly inefficient. This study proposed a non-invasive RF hyperthermia skin-tightening system with a compact metamaterial-filled waveguide aperture antenna. The proposed RF system increased the temperature by 11.6°C and 35.3°C with 20 and 80 W of 2.45 GHz RF power, respectively, within 60 s and exhibited a very focused effective area. Furthermore, a metamaterial was proposed to reduce the size of the waveguide aperture antenna and focus the electromagnetic field in the near-field region. The proposed metamaterial-filled waveguide aperture antenna was compact, measuring 10 mm × 17.4 mm, with a peak gain of 2.2 dB at 2.45 GHz. The measured hyperthermia performance indicated that the proposed RF system exhibited better power- and time-efficient hyperthermia performance than other RF hyperthermia systems in the cosmetic skin lifting commercial market. The proposed RF hyperthermia systems will be applied into a new generation of beauty cosmetic devices.

“…11 Energy devices, such as harmonic scalpel, are widely used in the field of otorhinolaryngology. It operates at a lower temperature (50°C-100°C) than other devices that are generally used at 150°C-400°C to minimize tissue damage 12 Unlike other instruments, scalpel cuts the tissue with the heat generated using vibration instead of electricity; therefore, it is used without muscle contraction. [13][14][15] Harmonic scalpel also has some positive reports that suggest that it achieves better results in term of less postoperative pain complains by patients.…”

A giant thyroid mass can be associated with severe compressive symptoms, requiring surgery for treatment. This paper reports the case of an 82-year-old man who presented with a giant thyroid mass that was suspected of being a metastatic papillary thyroid carcinoma on fineneedle aspiration cytology. A harmonic scalpel was used to excise the giant thyroid mass. A pectoralis major myocutaneous flap was used for reconstruction. The histopathology assessment confirmed the metastases in the lymph node and papillary thyroid carcinoma in the resected gland.

“…And a metal plate as a passive electrode that is in contact with the patient's skin, serving as a conductor. The energy passes between the electrodes and generates heat in the tissues [1,2,5,6,[16][17][18]. The two modes of capacitive or resistive treatment induce different tissue responses depending on the resistance of the treated tissue [6,19].…”

Electrophysical devices based on diathermy are one of the modalities used by many professionals to treat pain. The objective of this study was to identify the effects of Tecartherapy on healthy and unhealthy tissues. A systematic review of Tecartherapy technology was carried out. Articles published up to the year 2023 were investigated. The search argument used was "Capacitive-resistive electrical transfer" OR "Tecar" OR "Therapy Tecar" OR "CRET" in the BVS, Cochrane, PEDro, PubMed, IEEE Explore databases, Scielo and Web of Science. As for the main results of using Tecartherapy, there is an increase in temperature. In healthy tissues there is an increase in local blood flow, a decrease in muscle fatigue and an increase in muscle flexibility. In addition to the effects observed on healthy tissues, pain reduction and improved joint function were also observed. It was concluded that this technology has similar effects to other diathermy, but Tecartherapy proved to be safer and more comfortable.
