Bat wing sensory hairs likely help estimate aerodynamic forces for better flight control. Their distribution optimizes this sensory feedback, offering insights for bio-inspired sensor design.

Area of Science:

  • Biomechanics
  • Sensory Biology
  • Evolutionary Biology

Background:

  • The function of mechanosensors in bat wings is poorly understood.
  • Sensory hairs are densely distributed across bat wing membranes, but their arrangement principles are unknown.

Purpose of the Study:

  • To test if bat wing hairs provide strain information for aerodynamic force estimation.
  • To investigate if hair distribution is shaped by evolutionary pressures for sensory performance.

Main Methods:

  • Simulations of abstract wings with sinusoidal kinematics to establish scaling laws.
  • Hybrid simulations using bat wing models (spring-mass, blade-element aerodynamics) and empirical flight data.
  • Sparse sensor optimization techniques to identify optimal strain-sensing precision distributions.

Main Results:

  • Simulations show increased sensor needs for larger wings and higher aspect ratios.
  • Optimal sensor precision concentrates near wing boundaries, propatagium, and distal handwing.
  • Predicted optimal distribution patterns align with observed sensory hair arrangements in bats.

Conclusions:

  • Strain-based proprioception in bat wings aids flight performance.
  • Bat wing mechanosensation patterns suggest evolutionary optimization for sensory feedback.
  • Findings inform the design of bio-inspired flapping-wing sensing systems.
