Rigorous Clinical & Technical Standards

Since October 2023, Petal has been engaged in continuous sensor testing under the oversight of an Institutional Review Board (IRB). By utilizing pre-FDA submission guidelines, we ensure our data collection is ethical, scientifically sound, and aligned with industry-leading benchmarks.

Safety without compromise

Petal is guided by an unwavering commitment to the highest medical standards. Led by our Chief Medical Officer, Dr. Prionas—a breast radiation oncologist at one of the most prestigious medical institutions in the US—we ensure that clinical safety and medical accuracy are at the heart of every feature.

Medical-grade sensors

Petal uses advanced, medical-grade bio-impedance sensors—the same safe, non-intrusive technology trusted by medical professionals in clinical devices and BMI scales, but operating at significantly lower power.

Premium materials

Petal is crafted with premium, biocompatible materials, featuring soft European-knit fabrics and a polyurethane-coated interior that meets OEKO-TEX Standard 100 – a globally recognized certification ensuring they are tested for harmful substances and designed for safe, comfortable contact with your skin.

Safe communication

We use Bluetooth® Low Energy (LE) technology, one of the safest wireless technologies available, for seamless communication with the Petal app. It operates at an incredibly low power level—significantly lower than typical smartwatches and fitness trackers. Functioning entirely without Wi-Fi or cellular radios, it operates free of ionizing radiation.

our story

Petal was founded on the belief that women deserve more when it comes to their healthcare. Despite making up over 50% of the population, women have been systemically excluded from medical research, innovation funding and traditional health metrics. We’re here to change that reality.
