summary

A wearable prototype named Douleur chemically induces adjustable pain by pumping capsaicin via microneedling through a microfluidic reservoir and micropump while a Peltier temperature control adjusts skin heat. Two studies show pain intensity and quality scale with capsaicin concentration and temperature, and VR immersion rises (examples: scene immersion from ~1.2 to 5.4, others to 4.6 and 4.4). Device delivers controlled volumes and temps but needs single-use microneedles, shows habituation/analgesia risk, and requires 30–45 minutes to remove induced pain.
