Flexible & Stretchable Sensor Patent Snapshot 2026
The standalone flexible/stretchable sensor space is a small, fragmented corpus at maturity, with annual filings plateaued near their 2020 peak and no single applicant holding a commanding position. Force and pressure measurement (G01L) dominates the technology mix, while adjacent branches in textiles, polymer additives, and audio analysis remain sparsely filed.
A fragmented field with no dominant incumbent
The corpus is broadly distributed: the top-ranked applicants — TouchLab Ltd, Pegasus Solar Inc, and the Sharma individual-inventor group — each hold exactly 2 patent records, sharing the leading position with no clear hierarchy between them.
The top five filers account for 67% of the ranked applicants visible in this query’ combined total, a figure that sounds concentrated but reflects the very small absolute size of this corpus rather than entrenched incumbent control. No single organization has built a defensible lead.

The absence of a visible assignee creates a relatively open assignee snapshot: a well-resourced entrant investing in a focused technical sub-area could realistically claim a leading position without needing to displace an established patent holder.
Filings from 2024 onward are subject to standard publication lag and may be under-counted; the plateau reading should be confirmed once those records fully publish. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
Flat filing trend; force/pressure measurement anchors the technology mix
Annual filing volume and the IPC class distribution together reveal both the pace of activity and where technical effort is concentrated — or absent.
Annual filing trend
Activity first surfaced in 2020 with a three-record peak, fell back through 2021–2023, then returned to three records in 2024. The overall pattern is consistent with the maturity assessment: filings have plateaued near that 2020 peak rather than trending upward. Records for 2024 onward may still be entering the system due to publication lag and should not yet be read as a decline.

G01L (Force and pressure measurement) accounts for the largest share of IPC classifications, underscoring that pressure and tactile sensing is the established core of this space. G06F (digital data processing) and A61B (diagnosis and surgery) form a secondary cluster, reflecting sensor integration into computing interfaces and medical diagnostics. Branches such as D06M (textile chemical treatment), G01N (material analysis), and G10L (speech/audio) each appear only once, flagging them as under-served relative to the visible class.

Ranked by total forward citations. Citation counts favour older and broadly cited patent families, and broad or adjacent patents may appear when they match the search scope. Treat this section as citation context, not as a curated list of the most topic-specific patents. Some patent titles may be shown in their original, non-English language where an accurate translation could not be guaranteed.
Assignee snapshot from the current evidence set
The applicants below are visible in this query result. Because the evidence set is relatively small, read this section as a directional snapshot rather than a full competitive ranking.
TouchLab Ltd
TouchLab Ltd holds 2 patent records concentrated in G01L 1 and G01L 5 — force and pressure measurement — consistent with their focus on tactile sensing technology. Their technology profile is the most narrowly focused of the visible assignees, covering core sensing mechanics. Momentum data does not flag them as a new entrant, suggesting their filings represent established, rather than accelerating, activity.
patent records: 2Sharma Inventor Group (Dr. Anup Kumar Sharma and co-inventors)
The Sharma group — comprising Dr. Anup Kumar Sharma, Dr. Ritu Sharma, Mr. Atul Kumar Sharma, Mr. Puneet Sharma, and Miss Surbhi Singh — collectively accounts for 2 patent records filed as a multi-inventor team, all flagged as new entrants with a recent filing of 2 records. Their technical focus spans A61B 5 (medical diagnosis), B82Y 30 (nanotechnology), and C08L 83 (silicone polymer compositions), positioning them at the biomaterial and nanomaterial intersection of flexible sensing rather than pure transduction mechanics.
patent records: 2Frequently asked questions
The corpus contains 8 patent families in scope across four jurisdictions: the United States, India, China, and Australia.
TouchLab Ltd, Pegasus Solar Inc, and the Sharma individual-inventor group are all tied at the top with 2 patent records each. No single applicant holds a clear lead.
G01L (Force and pressure measurement) is the visible class, appearing in 7 of the patent records. G06F (electric digital data processing) and A61B (diagnosis and surgery) form a secondary cluster.
The field is assessed as at maturity, with annual filings having plateaued near their 2020 peak. There is no strong upward trend in recent years.
The United States leads with 4 patent records, followed by India with 3, China with 2, and Australia with 1. European jurisdictions and major East Asian offices beyond China are absent from this corpus.
Only one co-applicant relationship is documented: Sinopec (Beijing) Research Institute of Chemical Industry and China Petroleum & Chemical Corporation jointly filed 1 patent record. No cross-sector or cross-border co-filing is recorded, indicating that collaborative R&D networks here are nascent.

Patent data carries inherent limitations: recent filings (typically the most recent 18–24 months) are under-counted due to standard publication lag; counts may be reported at either a patent-family or a patent-record basis and are not always directly comparable; classification, applicant-name, and citation data may contain errors, duplicates, or omissions; and the underlying search query defines and constrains the scope shown. As a result, the analysis may be incomplete or inaccurate and may not reflect the full technology landscape.
