While the bioelectric potential is affected by living activities of the plant, it has been observed that the bioelectric potential can be reduced using plants. Thus, the influence of the life activity of a plant on the reception signal must be accounted for when a plant is used as a sensor. In this study, we produced an environmental change near a foliage plant growing in an indoor environment and examined the directivity of the plant\u2032s sensing ability. The sensitivity of the plant was a roughly circular area centered on the location of the plant. We also investigated the influence of the number of leaves on the plant on its sensing ability and found that it decreased with a reduction in the number of leaves. \nIn addition, we monitored the effect of a person walking on the spot near the plant on the bioelectric potential of the plant. Six subjects stepped on the spot 50\u2009cm from a rubber tree and we measured the variation in the bioelectric potential of the tree produced by this stepping motion. The results confirmed that stepping motion produces a measurable response in the bioelectric potential of a plant and that this response varies in synchrony with the subject\u2032s stepping rate. Moreover, by conducting principal component analysis using the peak value of the spectrum characteristics of the measured bioelectric potential, cumulative proportion was found to reach nearly 97% at low\u2010frequency components up to the fifth peak.<\/jats:p>","DOI":"10.1155\/2009\/917437","type":"journal-article","created":{"date-parts":[[2009,7,2]],"date-time":"2009-07-02T13:32:00Z","timestamp":1246541520000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Investigation of the Surrounding Environment\u2032s Influence on Gait Sensing Using a Plant as a Sensor"],"prefix":"10.1155","volume":"2009","author":[{"given":"Shigeki","family":"Hirobayashi","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yusuke","family":"Tamura","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kazuhiro","family":"Yamamoto","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2009,7,2]]},"reference":[{"key":"e_1_2_7_1_2","first-page":"395","article-title":"On radio regulation for protection of radio hazard to human body","volume":"43","author":"Suzuki T.","year":"2005","journal-title":"Transactions of Japanese Society for Medical and Biological Engineering"},{"key":"e_1_2_7_2_2","first-page":"Pr7\/189","article-title":"An inherent safety framework for dust explosion prevention and mitigation","volume":"12","author":"Amyotte P.
