Fit & Care
Sizing
Petal is one size. For the best accuracy, the sensors require snug contact with your body, so we recommend wearing Petal with a closer-fitting bra.
Cleaning instructions
Petal can be cleaned with any antibacterial wipe safe for use on the skin.
Materials
Bio-impedance sensors
Petal uses advanced, medical-grade bio-impedance sensors. This low-power technology safely measures your body's unique electrical resistance to gather data, making the measurements safe and non-intrusive.
Note: Petal’s sensors are only located on the left insert, as it’s closest to the heart. The right comfortable insert is included for balance and symmetry.
Fabric
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 for textiles tested for harmful substances and suitable even for baby products.

FAQ'S
Is Petal suitable for women of all ages?
Petal is designed to support women 18+, providing them with measurable health data related to their heart, mind, body and cycle.
Will Petal work if you’ve had a mastectomy?
Yes. The electrodes need to make good contact with your body, so we recommend wearing Petal with a closer-fitting bra.
Is it safe to wear Petal while pregnant or breastfeeding?
While Petal is safe to wear, we do not recommend wearing Petal when you are pregnant or breastfeeding, as changes in the fibroglandular tissue will cause the sensor readings to be inaccurate.
Can I wear Petal if I have a pacemaker or other implanted cardiac device?
No, we do not recommend wearing Petal with implanted cardiac devices such as a pacemaker or ICD.
Will Petal work with breast implants?
Yes, heart and mind metrics will function correctly; however, cycle and body composition metrics may be inaccurate.
Is Petal water-resistant?

Do I have control over my data? Do you sell my data?

If you consent, we will utilize anonymized and obfuscated health and demographic data for research purposes only.
