Researchers have demonstrated a wood-based device that senses pressure and heat through human contact. The prototype, called iWood, combines chemically modified wood with an ionic liquid to generate sensing signals. It points to a possible future for responsive floors or chairs, but it is not a clinically validated health monitor or a product readers can buy.
How can wood sense a person?
In the iWood research, the wood is chemically modified and infused with an ionic liquid. The device uses ions in the material alongside electrons in an electronic system to produce tactile-sensing signals. This iontronic approach makes the material part of the sensing process rather than just a passive surface.
Chemistry World reported on 3 April 2024 that the team demonstrated continuous capture of physiological signals through human contact. The reported capabilities are sensing pressure and heat changes when someone stands on the material or sits against it. The accessible report does not provide a clinical accuracy figure or diagnostic threshold.
Lead author Tingrui Pan described the principle this way: “We have ions, and the electrons that work together to produce tactile sensing signals.” Pan also characterized the broader interface idea: “We can actually get an interface between an artificial world like an iPhone and your natural world. This type of sensing is perfect to enable the traditional [wood] with new functionality.”

What health uses are possible—and what has been shown?
Pressure and heat sensing
The reported demonstration is contact-based sensing of pressure and heat. In principle, a wood surface integrated into a floor or chair could detect changes as a person stands or sits on it. Those are prospective forms discussed in the reporting, not established consumer products.
Motion and cardiovascular monitoring
The report identifies dynamic motion analysis and cardiovascular monitoring as promising directions. These are potential applications, not demonstrated clinical functions. The available evidence does not establish that iWood can diagnose a condition, replace a medical monitor, or provide clinically reliable measurements.

How mature is the iWood research?
The device is described in Li et al., “iWood: An intelligent iontronic device for human-wood interactions,” published in Advanced Functional Materials 34 (2024), article 2314190. The cited paper is also listed in a 2026 review of iontronic sensors. The accessible reporting and bibliographic identification establish the research demonstration, but do not establish safety validation, regulatory status, clinical performance, or commercial availability.

Iontronic pressure sensing is a broader research area that includes work on wearable and health-monitoring applications. That wider activity provides context for the field; it does not show that iWood itself is wearable or validated for health monitoring.
