Abstract
We have performed sequential studies on new types of soft rubber for their application as artificial skin in robots and haptic sensors. Based on a proposed electrolytic polymerization method and novel adhesion technique for rubber and a metal that utilizes a metal complex hydrate, we have developed an MCF rubber sensor. This sensor uses a magnetic compound fluid (MCF), natural rubber (NR-latex) or chloroprene rubber latex (CR-latex), and requires the application of a magnetic field. The potential application of the developed sensor in various engineering scenarios and our daily lives is significant. In this regard, we investigated the effects of γ-irradiation, infrared radiation, microwaves, and a thermal source on the MCF rubber sensor. We established that the MCF rubber is effective enough to be used for power generation of broadband electro-magnetic waves from γ-rays to microwaves, including the range of the solar spectrum, which is the typical characteristic obtained in the present investigation. The remarkable attribute is that the MCF rubber sensor dose is not degraded by γ-irradiation. We also demonstrated the effectiveness of the MCF rubber sensor in energy harvesting.

Rubber sensors are indispensable in a variety of engineering applications and affect many aspects of our lives
Based on the application of a magnetic field under the electrolytic polymerization to the soft rubber latex compounded with the magnetic compound fluid (MCF) (MCF rubber latex), these Fe3O4 and metal particles aggregate such that many magnetic clusters [9] are created to be aligned along the applied magnetic field lines like needles in the MCF rubber [1]
For a robot with an installed sensor operating in a nuclear reactor building, the typical characteristics of the MCF rubber sensor are that it is sensible for γ-irradiation enough to create the radiation power generation and that it is not degraded by γ-irradiation
Summary
Rubber sensors are indispensable in a variety of engineering applications and affect many aspects of our lives. The proposed novel adhesion technique is such that the MCF rubber with a metal complex hydrate is electrolytically polymerized under the application of a magnetic field, such that the metal electrodes can be adhered to the rubber. In the present report, we investigate the effect of γ-rays on the mechanical properties of an MCF rubber sensor under compression and tension. In the present report, we investigate the effect of infrared light on the MCF rubber sensor using an infrared heater, which has connection with the second source (thermal). In the present report, we investigated the effect of the thermal energy on the MCF rubber sensor using a heating plate. We investigate the effect of the microwave on the MCF diene rubber sensor by using a microwave oven. We clarify the effective possibility of the MCF rubber sensor in the energy harvesting
