Japanese researcher Kouhei Ohnishi unveiled on Friday an invention that wirelessly transmits force instantly between two devices. The development of this equipment allows physical therapists to treat patients better.

Force Transceiver

Ohnishi said that his ?force transceiver? provides a two ? way and real time communication between the applied pressure and resistance. The main purpose of this new invention is for the skilled operator to treat patients remotely by carrying out work using a robot in areas unsafe to people. Some factors to consider include areas with radiation or high temperature.

This wireless technology also allows physical therapists to transfer movements without any delay.

For instance, the therapist will have an idea about how well the patient?s limb is moving. This is an important piece of information that should be strictly monitored.

Reduce Burden to Medical Care Professionals

Ohnishi, a system design professor at Keio University, sees this newest technology as a way to lessen the burden on medical care professionals, while increasing treatment convenience to patients.

The device could also diminish or amplify the applied force, he said. It can be used to do construction work that humans are unable to do.

This is because the device uses a high ? speed wireless communication and computation system that moves extremely faster than the current wifi technology for domestic Internet use.

A Demonstration

Ohnishi?s team did a demonstration of his invention by presenting two box ? like tools that have levers on top. Once the user moves the lever on one unit, the lever on the other will move exactly the same force and speed instantly. It works as if both units were physically connected.

The demonstration used a fork and an apple placed on one of the devices. An AFP reporter used the lever on the other device to push the fork into the fruit. The reporter felt the resistance on the apple?s skin when the fork penetrated it.

To Preserve Techniques

The Japanese researcher sees the use of the device in the future to preserve the techniques of highly skilled craftsmen. One example is the skill of a master lens grinder, who applies different levels of pressure when he works.
