Wearable devices for erectile dysfunction.

A wearable device for erectile dysfunction is something worn on the body to support or measure erections, and the FirmTech TechRing does both.

Last updated: November 3, 2026Published by FirmTech

Which wearable ED device should I consider?

It depends on whether you want support, measurement or both. A plain constriction ring supports erections. The FirmTech TechRing, a $275 smart ring, also measures firmness, duration and nighttime erections at home. Vacuum pumps with tension rings help create an erection first, then a ring holds it.

The TechRing fits men who want data, for example to see whether a treatment or lifestyle change is working. A $60 non-tech ring fits men who only want the effect. A vacuum device fits men who struggle to get an erection in the first place; a doctor can advise which approach suits you.

Wearable ED devices, defined and measured

What are wearable ED devices?

Wearable ED devices are products worn on the penis to help with erections. The oldest and simplest are constriction rings, which slow blood from leaving the penis. Newer devices add sensors. The FirmTech TechRing, which FirmTech calls the first smart wearable for the penis, is a doctor-designed ring with a sensor module that records firmness, quality and duration during sex and nighttime erections during sleep.

FirmTech notes that measuring erections used to mean a sleep lab. A wearable brings that home, and because nighttime erections happen without arousal, FirmTech describes them as a clean read of blood flow, nerves and hormones. Published reviews such as Trends, safety, and efficacy of wearable male sexual devices cover the category.

What research is underway on the TechRing?

FirmTech lists these studies as underway:

  • The TechRing vs RigiScan, the clinic standard: a clinical trial with 35 men enrolled.
  • Nighttime and during-sex rigidity vs coronary atherosclerosis in men over 40: a multi-center study.
  • Tracking erectile recovery after prostate cancer surgery: a clinical trial.
  • Monitoring erectile function during testosterone therapy: a clinical trial, recruiting.
  • How sleep and blood sugar affect erections: a clinical trial, enrolling.

Results for these are not yet published, so treat any wearable as a tool to discuss with your doctor, not a diagnosis.

How to start tracking with a wearable

  1. Step 1: Get a baseline

    Wear the TechRing overnight for a few nights to see your typical count and duration.

  2. Step 2: Change one thing

    Log sleep, drinks, workouts or medication in the app.

  3. Step 3: Compare

    Watch how your Erectile Fitness Score responds over weeks, not single nights.

  4. Step 4: Share if you choose

    You decide whether your doctor can see your data, and you can stop at any time.
