SmartSlab Table

The SmartSlab Table signals the arrival of intelligent materials in furniture design and architecture, unlocking a wide range of potential applications – in this instance, a table that can warm plates, cool a drink, and even cook a meal.

First shown at the Salone del Mobile in April 2016, the SmartSlab Table uses discreet digital devices embedded in a razor-thin, ceramic table-top in order to control temperature at various points across the table’s surface.

The table acts as a testing ground for SmartSlab, a new composite material developed by KRAM/WEISSHAAR for the Iris Ceramica Group.

The SmartSlab Table features key SmartSlab functions such as through-panel touch control, heating, cooling and inductive cooking in a single composite slab that acts simultaneously as circuit board, structure and surface.

Inductive Cooking
Magnetic induction cooking provides faster heating, improved thermal efficiency, and more consistent heating than cooking by thermal conduction, with precise control similar to gas. Where induction cookers typically have glass ceramic tops, SapienStone provides an improved surface with a greater potential for seamless integration in a large surface area. The SmartSlab system allows induction coils to be positioned directly beneath the SapienStone surface, meaning the slab itself is activated for cooking.

Touch Interface
A custom designed capacitive sensing unit is integrated into the SmartSlab panel. It detects pressing or tapping gestures on the ceramic surface. A light-pipe made of acrylic glass conducts and diffuses light from LEDs evenly through the SmartSlab panel. When a user slides over the specified area of the interactive ceramic tile, a light-feedback shines through the ceramic material, responsively tracking the position of the user’s finger.

Heating
A resistive, screen printed metal spiral heats up to 120°C when electrical current is applied. The outer silicone coating acts as a durable electrical insulator while conducting heat to the ceramic surface it is attached to. Silicone coating makes it possible to keep elements extremely slim while an additional layer of foam doubles as both heat insulation and a structural component of the SmartSlab composite adding stiffness to the table top.

Cooling
By applying a specific current to the two different semi-conductor materials, peltier devices transfer heat from one side of the element to the opposite, cooling the first side down and vice versa. To keep cooling-flux constant, the hot side is cooled by ventilation in the backbone of the table that acts as a giant heat sink.

Constructed at a specially created lab within the Iris Ceramica factory in Modena, SmartSlab integrates heating, cooling, and sensor technology directly into oversized ceramic panels.

The top layer of the SmartSlab composite is made of SapienStone, a virtually indestructible ceramic material impervious to fire, frost, thermal shock, scratches and microbes. The unique composition and structure of SapienStone makes it particularly adaptable and allows for a multitude of uses from furniture and interior fit outs to architectural structures.

To demonstrate the abilities of the SmartSlab Table, KRAM/WEISSHAAR collaborated with the celebrated chef Massimo Bottura to hold two dinners on consecutive nights in Milan’s Palazzo Clerici.
