Deepinder Goyal Says Temple Wearable Is Now Much Smaller
Temple is a small wearable device designed to sit near the side of a person’s head.
Its creator, Deepinder Goyal, says the newest version is less than half the size of earlier versions.
He also calls it the smallest wearable by volume and the most powerful version so far.
The device is meant to measure blood flow in the brain.
It also produces a score called Entropy, which Goyal says reflects the body’s energy use or metabolic state.
The company says the score can change with things such as sleep, exercise, stress, meals and caffeine.
Temple is being tested and has not yet shared all of its technical details or official performance comparisons.
Pre-orders for a limited edition are expected soon, with shipping planned before the end of 2026.
Deepinder Goyal says Temple is now less than half the size of earlier prototypes.
Goyal describes the device as the smallest wearable by volume and its most powerful version yet.
Temple is designed to monitor cerebral blood flow and a biomarker called Entropy in real time.
Limited-edition pre-orders are expected soon, with shipping planned before the end of 2026.
Temple remains under early-access testing, with technical details and official benchmarking data not yet released.
- Who
- Deepinder Goyal and his research initiative, Continue Research, are developing Temple.
- What
- Temple is an experimental, research-grade wearable that monitors signals near the temple, including cerebral blood flow and the Entropy biomarker.
- When
- Goyal said pre-orders would open soon and shipping was expected before the end of 2026; the device remains in early-access testing.
- Where
- The device is worn near the side of the head, close to the temple.
- Why
- Goyal presents Temple as a wellness product intended to provide information about stress, neurological health and the body’s metabolic state.
Company Claims
Evidence Limitations
Size and capability
Company Claims
Goyal says Temple is less than half the size of earlier prototypes, the smallest wearable by volume and the most powerful version yet.
Evidence Limitations
The company has not provided specific measurements explaining the reduction in size, so the claims cannot be independently assessed from the available information.
Entropy measurement
Company Claims
Temple says Entropy provides a real-time indication of metabolic activity and may be more accurate than heart rate for assessing energy use.
Evidence Limitations
Temple has not disclosed how the score is generated or calculated and has not released official benchmarking data.
Product readiness
Company Claims
Goyal says limited-edition pre-orders will open soon and shipping is expected before the end of 2026.
Evidence Limitations
The wearable is still under early-access testing, and Goyal previously said the science would be shared when the product was available for sale.
