Eternal's Deepinder Goyal details how his new Temple health wearable stays on the skin

Device Details

Deepinder Goyal has answered questions on social media about his upcoming health wearable device, Temple, addressing user concerns on sticky grip tapes, daily water use, and comfort during exercise. The Zomato founder and Eternal Vice-Chairman stated that the gadget uses single-use adhesive tapes, and buyers get an endless supply of them included in the price. Goyal posted his replies on October 3 following an online query from a user named @tyags6 about how the device fastens to the skin and handles water exposure.

Use And Wear

The device is built to stay firmly in place while users run, jump, swim, shower, or use a sauna, though it cannot be used for scuba diving. Users must put on a fresh tape each time rather than reusing an old one. While the battery lasts for about seven days and some users keep a single tape on for that long, the maker advises swapping the tape every two to three days. The unit features smooth edges so that clothing like T-shirts can slide over it without pulling it off. Goyal also mentioned that people can wash their face, apply makeup, and carry out regular skincare routines without trouble.

Launch Plans

Temple is a compact sensor placed near the head to track blood flow in the brain in real time for insights into aging and brain health. It is being built under Eternal through Goyal's personal research project, Continue Research, backed by $25 million of his own money, and is entirely separate from Zomato. Goyal revealed six launch colors earlier: True Gold, Rose Gold, Dark Mirror, Real Jade, Deep Blue, and Purple Funk. Pre-orders will start soon, with first-in-line access given to people on the early-access waitlist.

Context

Wearable health gadgets are becoming more popular for tracking personal fitness and vital signs outside of traditional medical settings. Developing a device that attaches securely to the skin without causing irritation requires specialized medical-grade adhesives. Independent research ventures by prominent tech founders often focus on experimental health and longevity projects.
