Japan develops miniature sensors that are as light as a drop of tears and can be measured in the human body.

Not long ago, Harvard University and MIT collaborated to develop an artificial muscle that can lift a thousand times heavier than it, and Nagoya University in Japan did not give up, and developed a sensor measuring only 2 mm in size. A drop of tears, weighing human weight, can measure the data, which is much stronger than the same type of sensor.

According to Japanese media reports, this sensor was developed by Professor Shinji Shiji of the Graduate School of Engineering, Nagoya University, and Assistant Professor Yosuke Masaaki. In addition to measuring weight, it can also measure a wide range of data such as hardness, pressure and pressure. .

Don't underestimate this sensor with an area of ​​only 2 mm, the main components are basically placed. It is reported that its weight measurement range is a minimum of 0.04 grams, the maximum is 61.18 kilograms, the measurement range is wide, about 1000 times that of the same type of sensor. In theory, a 30-gram rat and a 30-ton tram can rely on the same sensor to measure the result.

In addition, in order to avoid the measurement effect caused by temperature changes, the sensor uses quartz to support the oscillator, and specially designed the alignment part. Even at a temperature change of 1 ° C, only a deviation of about 0.1 gram is produced.

It is reported that Professor Shinji is a member of the Institute of Electrical and Electronics Engineers (IEEE) and has been focusing on microelectromechanical systems (MEMS) and robotics to control the study of tiny objects such as cells. He said that the future goal will be to cooperate with the quartz oscillator manufacturer to reduce the cost of the sensor from the unit price of 1,000 yen to tens of yen. It is expected to be put into practical use and mass production in 2018. It is expected to be used in equipment represented by robots.
