This underscores the importance of in situ resource utilization (ISRU) strategies that convert planetary resources into functional electronic components. In this work, we harness the dielectric characteristics of Martian regolith (MR) simulant to create an MR\/polydimethylsiloxane (PDMS) composite film with enhanced triboelectric properties. Structural and morphological analyses of the MR reveal multiple oxide\u2010rich phases, which improve both the dielectric properties and the surface microstructure of the MR\/PDMS composite film. The resultant MR\/PDMS composite film\u2010based triboelectric nanogenerator (TENG) delivers an approximately two\u2010fold increase in open\u2010circuit voltage compared to the pristine PDMS\u2010based TENG. The real\u2010world use of the MR\/PDMS TENG is further demonstrated by proof\u2010of\u2010concept applications: a glove\u2010mounted tactile surface sensor with wireless signal transmission and a wearable triboelectric keypad. This work not only showcases advances in MR\u2010based TENG performance but also marks the first demonstration of triboelectric applications using MR simulants as functional triboelectric material. Additionally, we have demonstrated foundational work toward ISRU\u2010oriented tactile interfaces incorporating MR\u2010simulant\u2010derived functional materials for future controlled habitats and robotic platforms relevant to future space exploration.<\/jats:p>","DOI":"10.1002\/smll.74734","type":"journal-article","created":{"date-parts":[[2026,8,3]],"date-time":"2026-08-03T07:59:39Z","timestamp":1785743979000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Martian\u2011Regolith Simulant Confined Nanogenerators for Wireless Tactile Sensing for Human\u2010Machine Interface"],"prefix":"10.1002","volume":"22","author":[{"given":"Shidhin","family":"Mappoli","sequence":"first","affiliation":[{"name":"Future Energy and Innovation Laboratory Central European Institute of Technology, Brno University of Technology  Brno Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Keval K.","family":"Sonigara","sequence":"additional","affiliation":[{"name":"Future Energy and Innovation Laboratory Central European Institute of Technology, Brno University of Technology  Brno Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5846-2951","authenticated-orcid":false,"given":"Martin","family":"Pumera","sequence":"additional","affiliation":[{"name":"Future Energy and Innovation Laboratory Central European Institute of Technology, Brno University of Technology  Brno Czech Republic"},{"name":"Office of Research and Development Asia University  Taichung Taiwan"},{"name":"Faculty of Electrical Engineering and Computer Science VSB\u2010Technical University of Ostrava  Ostrava Czech Republic"},{"name":"Department of Medical Research China Medical University Hospital China Medical University  Taichung Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,8,3]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1038\/s41467\u2010023\u201038676\u20102"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1038\/s41550\u2010022\u201001851\u20104"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.34133\/2021\/9820546"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.1038\/srep44931"},{"key":"e_1_2_9_6_1","doi-asserted-by":"publisher","DOI":"10.1038\/s41598\u2010025\u201007901\u2010x"},{"key":"e_1_2_9_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.radmeas.2020.106247"},{"key":"e_1_2_9_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.radmeas.2009.01.010"},{"key":"e_1_2_9_9_1","doi-asserted-by":"publisher","DOI":"10.1002\/admt.201800487"},{"key":"e_1_2_9_10_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.nanoen.2023.108787"},{"key":"e_1_2_9_11_1","doi-asserted-by":"publisher","DOI":"10.1038\/s41467-019-09461-x"},{"key":"e_1_2_9_12_1","doi-asserted-by":"publisher","DOI":"10.1002\/aenm.202101170"},{"key":"e_1_2_9_13_1","doi-asserted-by":"publisher","DOI":"10.1038\/s41467\u2010021\u201025046\u2010z"},{"key":"e_1_2_9_14_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.apmt.2025.102919"},{"key":"e_1_2_9_15_1","doi-asserted-by":"publisher","DOI":"10.1080\/17452759.2025.2457580"},{"key":"e_1_2_9_16_1","doi-asserted-by":"publisher","DOI":"10.1002\/advs.202206243"},{"key":"e_1_2_9_17_1","doi-asserted-by":"publisher","DOI":"10.1007\/s40145\u2010021\u20100482\u20101"},{"key":"e_1_2_9_18_1","doi-asserted-by":"publisher","DOI":"10.1039\/D4TA08440C"},{"key":"e_1_2_9_19_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.nanoen.2024.109943"},{"key":"e_1_2_9_20_1","doi-asserted-by":"publisher","DOI":"10.1038\/s41598\u2010025\u201000686\u2010z"},{"key":"e_1_2_9_21_1","doi-asserted-by":"publisher","DOI":"10.1021\/acsaelm.3c01428"},{"key":"e_1_2_9_22_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.nanoen.2019.02.058"},{"key":"e_1_2_9_23_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.nanoen.2025.110661"},{"key":"e_1_2_9_24_1","doi-asserted-by":"publisher","DOI":"10.1002\/adem.201700275"},{"key":"e_1_2_9_25_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.xcrp.2023.101320"},{"key":"e_1_2_9_26_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.nanoen.2014.01.001"},{"key":"e_1_2_9_27_1","unstructured":"D.
