I've also written a short recap of our work on my website. Check it out if you're interested: torsalve.xyz/publications/ultrasound-chemicals

Thanks a lot to my brilliant co-authors, @arpitbhatia.bsky.social, Lei Gao, Ryuji Hirayama, Sriram Subramanian, Joanna Bergström and @khornbaek.bsky.social, who all put a great deal of time and effort into the project!

🚀 Why It Matters:
- Non-contact delivery/modulation opens new possibilities for haptic tech.
- Allows dynamic control of chemical stimulation.
- Impacts study of chemical/mechanical sense interactions.
- First digital control of chemical stimulation for haptic feedback.

🔍 Achievements:
- Non-contact delivery of chemical stimulants (menthol, capsaicin, cinnamal, ethanol) using acoustophoresis.
- Ultrasound-delivered droplets produce haptic sensations.
- Ultrasound increases perceived intensity.
- Cinnamal + ultrasonic feedback enhances perception.
