初年度は、胎動の有無に加え腹部の胎動の場所を客観的に計測するためのセンサの開発を行った。妊婦帯に圧力センサを複数配置することで、妊婦の腹部皮膚表面に現れる胎動を計測計測する。妊婦帯には株式会社ロースマダムのワンタッチ妊婦帯 幅広タイプを用いた。圧力センサにはInterlink Electronics社製FSR406を用いた。圧力センサ１個の大きさは43.7 x 43.7mm、感圧領域は40 x 40mmである。妊婦帯に上下左右隣り合う距離が等しくなるように約6cm間隔でFSR406を11個配置した。得られた圧力センサ群のデータは、M5Stackを用いて60Hzで計測が可能である。SDカードに記録可能であり、32GBのSDカードでは約222日間記録することができる。予備実験において、装着者の微動な身動ぎなどでも圧力センサが反応することを確認している。そこで予期せぬ体験者の身動ぎを計測するために3軸の加速度センサも配置した。また、計測した胎動データを腹部3Dモデルにマッピングし、胎動の動きも視覚化できる胎動ディスプレイの開発も行った。腹部に搭載したLEDマトリックスにて計測した胎動データを可視化できる。また既に記録したデータだけでなく、リアルタイムに表示することも可能である。また、1日分の胎動を1分で再生するなど、計測した胎動を指定した時間軸で胎動を再現することもできる。胎動スキャナを用いて実際に胎動を計測できるのか実験をおこなった（１名のみ）。結果、胎動と思われる圧力の変化を確認することができた。開発した胎動スキャナを用いることで、皮膚表面に発生する胎動を客観的に計測できることが示唆された。

At the beginning of the year, there are no plans to increase the number of passengers in the places where the abdominal tire is located, and there are no plans to do so. The pregnancy stress test is used to determine the number of pregnant women, and the fetal movement meter is displayed on the surface of the abdominal skin of pregnancy. Pregnancy, pregnancy and pregnancy. Please use the Interlink Electronics FSR406 to help you. The number of employees is 43.7 x 43.7mm and the field of perception is 40 x 40mm. There are 11 FSR406 configurations between pregnancy and other health care stations, such as 6cm. You have to use the 60Hz to calculate the number of people you need to know, and the M5Stack to calculate the possibility of failure. The SD record may be bad, while the 32 GB SD record may be bad for about 222 days. In order to make sure that you are not in the market, the equipment and the device will do everything in your power to make sure that you are not in trouble. It is expected that the health care worker will be able to perform an acceleration test in order to configure the equipment. The baby, the baby, the abdomen, the abdomen, the abdom The abdomen should be operated on the LED train. The fetal movement should be made available to you. This means that it is possible to tell you that it is possible to tell you that it is possible. On the 1st, 1st, 1st, 2nd, 1st, 2nd, 2nd, 2nd, 2nd, 2nd, 2nd, 2nd, 2nd, 2nd, 2nd, 2nd, 2nd, 2nd, 2nd, 2nd, 2nd, 2nd, 2nd, 2nd, 2nd, 2nd, 2nd, 2nd, 2nd, 2nd, 2nd, 2nd, 2nd, 2nd, 2nd, 2nd, 2nd, 2nd, 2nd, 2nd, 2nd, 2nd, 2nd, 2nd, 2nd, 2nd, 2nd, 2nd, 2nd, 2nd, 2nd, 2nd, 2nd, 2nd, 2nd, 2nd, 2nd, 2nd, 2nd, 2nd, 2nd, 2nd, 2nd, 2nd, 2nd, 2nd, 2nd, 2nd, 2nd, 2nd, 2nd, 2nd, 2nd, 2nd, 2nd, 2nd, 2nd, 2nd, 2nd, 2nd, 2nd, 2nd, 2nd, 2nd, 2nd, 2nd, 2nd, 2nd, 2nd, 2nd, 2nd, 2nd, 2nd, 2nd, 2nd, 2nd, 2nd, 2nd, 2nd, The number of fetal movements is very high, and the number of people involved in fetal movement is very high. Results: the results showed that the thought of fetal movement confirmed that there were significant differences between the two groups. The use of an instigation device on the surface of the skin or on the surface of the skin should be used to indicate the use of an abettor.
