SU-8 force sensing pillar arrays for biological measurements

Open access

Abstract

The generation and sensation of mechanical force plays a role in many dynamic biological processes, including touch sensation. This paper presents a two-axis micro strain gauge force sensor constructed from multiple layers of SU-8 and metal on quartz substrates. The sensor was designed to meet requirements for measuring tactile sensitivity and interaction forces exerted during locomotion by small organisms such as the nematode Caenorhabditis elegans. The device is transparent and compatible with light microscopes, allowing behavioral experiments to be combined with quantitative force measurements. For the first time, we have characterized the scale of interaction forces generated in wild-type C. elegans in probing and responding to their environment during locomotion. The device features sub-microN force resolution from 1 Hz to 1 kHz, >25 microN range, kHz acquisition rates and biocompatibility.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The force exerted by C. elegans as it moves against a microfluidic pillar was recently reported to be 2.5 ± 2.5 μN.

    “Indeed, the force exerted by C. elegans as it moves against a microfluidic pillar was recently reported to be 2.5 ± 2.5 μN (Doll et al., 2009).”

    From Gait Modulation in C. elegans: An Integrated Neuromechanical Model (2012) · cites this paper as Doll et al., 2009

    The Results and discussion (C. elegans force generation) report a mean peak contact force of 2.5 ± 2.5 μN for freely moving wild-type worms. The Experimental setup and preparation section describes worms contacting force-sensing pillars positioned near an agar surface; it does not establish that the pillars were microfluidic.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
